Best streamer: Amazon Fire TV Stick 4K
Amazon's best streaming stick, the Fire TV Stick 4K does exactly what that unimaginative name suggests.
It's cheaper than the new second-gen Fire TV Cube, but still gets you high end features like 4K streaming, HDR10+ and Dolby Vision.
The Stick 4K has a power cable and is slightly longer than last year's but is easy to plug and play ‚Äď if you need it at an angle, there's a dongle to help. It gets you access to services including Prime Video, Netflix, HBO, Hulu, BBC iPlayer, Disney, Curzon, Plex and more ‚Äď a very solid selection in both the US and UK.
Equally important is the bundled Alexa remote which Amazon is selling separately in the US for $30. You can hold down the button instead of saying "Alexa" and there are IR control and volume buttons which can be used to control your TV, soundbar or AV receiver.
Unlike the Cube, keep in mind the Fire TV Stick 4K won't act as an Echo when the TV is off. But when surfing results it's generally really quick, with some room to improve on Netflix.
In use, it's faster and smoother all round thanks to a new quad-core 1.7 GHz processor inside. Fire OS has its positives and negatives ‚Äď it's easy to use but a bit cluttered and we'd quite like the ability to customize it a little more.
It's packed with features and services, its 4K streaming is excellent and Dolby Atmos is also on board to give you a sound boost. When it comes to HDR10+ and particularly Dolby Vision, though, we couldn't find many movies and shows that support it yet ‚Äď Apple's library is better served on the Dolby front, for instance.
Overall, though, this is an affordable and future-proof streaming stick option.
What we love
- Great value
- Lots of features and services
- IR Alexa remote
What we don't love
- UI needs work
- Lack of Dolby content
- Netflix can be slow

Runner-up: Apple TV 4K
Less of a streaming stick and more of an ultra high definition Pandora's Box, the Apple TV 4K is a seriously smart TV companion.
As you‚Äôd expect from Apple, this richness comes from the host of apps, accessible from the Apple TV‚Äôs own App Store. The majority of these include the full range of content streaming platforms, both free and paid-for, live TV services and ported iOS games.
Packing everything into the diminutive little black box, the Apple TV 4K is powered by a new A10X chip to handle all the 3840 x 2160 Ultra HD grunt. And there‚Äôs plenty to choose from, with Amazon Prime Video, Netflix and iTunes, all with growing reasonably priced 4K libraries. The only downside is that YouTube 4K isn't supported, so you'll have to settle for 1080p for now.
However, you are getting support for HDR10, Dolby Vision HDR (High Dynamic Range), Dolby Digital Surround sound and Dolby Atmos audio. The last of those really confirms the Apple TV 4K as an AV powerhouse, but you'll still need the right TV and speakers to make the most of these features.
Siri is also well integrated, and offers more contextual options than you might think, even if, yeah, Siri still pales in comparison to Alexa and Assistant.
Apple TV, as you'd expect, plays nicely with AirPlay 2 as a receiver and sender, so you can send the sound to an AirPlay speaker, or, preferably, a sound bar, by dragging down on the remote. And, if you're streaming video on a Mac, iPhone or iPad, you'll be able to ping those visuals over to your Apple box.
The box also has the ability to act as a HomeKit hub, automating actions based on your location.
There is one niggle though, as Apple has announced that its TV app and TV+ streaming service will make its way to every other streaming device. This will take some advantages away from the Apple TV 4K, but it's still a great piece of kit.
What we love
- Simple, intuitive interface
- AirPlay and HomeKit support
- Dolby Vision and Dolby Atmos
What we don't love
- Comparatively pricey
- Fiddly remote
- Siri is still just Siri

Best for Android lovers: Google Chromecast Ultra
Despite working in a very similar way to its competition, the way you use the Chromecast Ultra isn‚Äôt quite plug and play. Instead of using a central interface on your TV with a bundled remote, you use your mobile device and the apps you have installed on it to find things.
It connects to your TV via HDMI, can stream 4K HDR content up to 2160p (in both HDR10 and Dolby Vision) and requires power via a spare plug socket (it needs more power than your TV can provide).
The Google Home app has a go at suggesting popular content that might be of interest, but it‚Äôs not personalized to what you‚Äôve watched previously, like the Amazon Fire TV.
You‚Äôll get more of that from going into the apps directly. However you go about finding content, once you have something you want to watch, you‚Äôll use the ‚Äúcast‚ÄĚ icon to throw this content from your device to the TV.
Once it‚Äôs there, the Chromecast Ultra does all the work for you ‚Äď you can continue to use your device for other things, listen to music with it or even turn it off, and the program will continue to play.
There is one sticking point here. Not all apps play nicely with Chromecast, and Amazon is one of them. With a fairly limited amount of 4K content available to stream at the moment, and Amazon offering a decent chunk of it, that‚Äôs a bit of a blow for the Chromecast Ultra‚Äôs capabilities. There is a hack you can use to cast from a Chrome browser, but it‚Äôs not as slick, and won‚Äôt do playback in 4K.
Still, there‚Äôs a wealth of 4K HDR programming on Netflix and YouTube that does work with casting, plus a handful of films to buy from Google Play.
Being part of the Google ecosystem also gives it some pretty hefty smart home points to stick it to the competition, with the ability to ask any smart speaker with Google Assistant built in to play something on your TV.
What we love
- Flexible 4K HDR streaming
- Google Home integration
- Ethernet port for hardwiring
What we don't love
- No home screen interface
- No Amazon support
- Needs a spare plug

Best budget pick: Roku
From ¬£29, Amazon
If you already have a smart 4K TV, you'll already have apps onboard, so why buy a streaming stick on top of that?
Roku has created a platform that offers you more for your buck and covers a range of price points, starting at just ¬£29 for the new Roku Express.
The Roku Streaming Stick+, pictured above, costs ¬£59 and therefore makes it a more expensive pick, but offers 4K, HDR10 streaming and ‚Äď appeal number one ‚Äď takes speeds to a new level thanks to a clever Wi-Fi upgrade.
By putting the antenna in the cable, rather than the stick which sits behind the signal-blocking TV, Roku has managed to enhance speeds by up to four times. This means the 802.11ac dual-band MIMO is likely faster than your TV and results in quality streaming without buffering.
Reason two for shelling out for this stick is to have all your favorite streaming apps anywhere you go ‚Äď a hotel with work or a buddy's house for a binge viewing session. Roku has the holy trinity on board: Netflix / Prime / Google Play. Sure, there's no iTunes, but you'll never see that anywhere other than Apple and Samsung devices. And it's all so easy to use.
Plug into the TV via HDMI and the stick will automatically work out what the TV can handle and set up the output signal to max ‚Äď which tops out at 4K and HDR running at 60fps. But this is also smart enough to pair the included remote with that TV model meaning you can control things like volume from the remote.
You also won't need to plug this one into an outlet, as it uses a USB cable to plug directly into the back of your TV. That's an easy option, though you will need a TV that has a USB socket on the back. One gripe here is that Alexa and Google Assistant don't work great.
They'll open apps and find movies and TV shows fine, but playing and pausing is a bit glitchy. There's also no Dolby Vision support, which makes the Stick+ feel dated compared to the Apple TV 4K and Fire Stick 4K.
Other positives includes the accompanying smartphone app, which lets you listen via your headphones wirelessly, a reliable casting option from your smartphone and the Vudu app, which has a large catalogue of 4K HDR movies.
What we love
- Super simple to use
- Good performance
- Great range of apps and services
What we don't love
- Alexa and Google Assistant are glitchy
- No Dolby Vision
- No Apple/iTunes support

Best for UK streamers: Now TV 4K Smart Box
Sky's own Now TV services currently stream in 720p, so what's it doing launching a 4K streaming box? Well, the addition of Netflix to the platform goes someway to explaining that.
If you're in the UK and you're looking to be completist about your streaming services, Netflix was the big, missing piece for Now TV. (Though Amazon Prime Video remains MIA, as do Google Play Movies, Spotify etc).
So, if you go for the 4K Smart Box, you can now watch 4K movies and TV shows from Netflix in 60fps or watch 4K HDR YouTube content in 30fps. Here, 4K Netflix looks as nice and crisp as you'd expect, but you really can get that from a lot of other streaming sticks, devices and TVs, too.
Everything else in terms of third-party apps ‚Äď BBC iPlayer, ITV Hub, All4, Demand 5 - streams in 1080p, and the 720p streaming on Now TV is fine, but a shame if you're spending money on that Sky Cinema Pass.
It's all very easy to set up and use, the bundled remote works well and voice search is OK, though certainly not best in class. The service's UI has always been a little slower than its rivals, but nothing you'll find too irritating and the 4K Smart Box does improve on the Smart Stick slightly on performance.
All in all, the Now TV 4K Smart Box has put itself in a tricky spot. You still get the no contract access to Sky's Cinema selection, Entertainment box sets (HBO shows etc), Kids, reality TV on Hayu and ‚Äď a biggie ‚Äď Sky Sports.
But, Netflix is available on the cheaper Smart Stick, too, and if you care about picture quality, why would you accept lower resolutions for Now TV's main selling point, the Sky packages?
That said, if you want Sky Sports (or the other two passes) + Netflix and you're willing to wait for Sky to catch up on resolution, this is still a beginner-friendly, affordable option.
What we love
- Easy to use
- Sky's great passes
- Netflix in 4K
What we don't love
- No Prime Video/Google Play
- Now TV isn't 4K
- Voice could be better
Streaming devices: What to consider before buying
1. Streaming services
The services you're signed up to - or want to sign up to - is arguably the most important thing to consider when purchasing a streaming device.
Netflix and Amazon Prime Video are the two heavyweights, but there's also apps like Hulu, Now TV, Mubi and Spotify to consider. If you just want to get these services onto your TV, with no fuss on specs or resolution, you can pick up a bargain streaming stick ‚Äď an original Chromecast say or a Now TV Smart Stick ‚Äď and away you go.
Do you need a nicely designed home screen, or are you happy firing up an app on your phone? Do you actually care about voice controls from the remote?
2. 4K, HDR and other specs
If you've got a high-spec TV, or you're forking out for 4K Netflix, say, then you'll need to look a bit further. Does the box or stick support 4K streaming, or even HDR10, to make it future-proof?
There are also some gaming focused options like the Nvidia Shield TV ‚Äď does Android gaming and a bundled controller sound like fun?
3. Streaming devices as smart home hubs
A simple streaming accessory can turn your TV into your smart home hub. Apple TV 4K is there for HomeKit users, the Chromecast Ultra and Chromecast (2018) represent Google Assistant and Amazon's Fire TV range is Alexa-enabled.
Make your choice carefully, based on what other smart kit you have in the house that's connected to one of the big three ecosystems. This area is only going to expand.
Smart support through the TV doesn't have to come from a streaming device, as you can also install a smart soundbar that houses a voice assistant, but it's definitely worth looking into.
