The Google TV Streamer 4K is the better pick for buyers who want the best Dolby Vision streamer because it pairs 32 GB of storage with 4 GB of RAM, while the Xiaomi TV Stick 4K (2nd Gen) suits travelers with its 28 g body and the Roku Ultra suits anyone who wants a rechargeable backlit remote. The Google box carries 32 GB of storage and 4 GB of RAM, the Xiaomi stick carries 8 GB and 2 GB, and the Roku Ultra adds an Ethernet port plus Wi-Fi 6.
- Choose the Google TV Streamer 4K if you install lots of apps and games — 32 GB of storage and 4 GB of RAM keep it roomy.
- Choose the Xiaomi TV Stick 4K (2nd Gen) if you stream on the road — it weighs just 28 g and supports Dolby Vision and HDR10+.
- Choose the Roku Ultra if you want a wired connection and a remote you never have to charge by hand — Ethernet plus a rechargeable backlit remote.
I compared these three on picture formats, memory and storage, and connection options, using only the listed specifications. Dolby Vision support, RAM and storage, and Ethernet versus Wi-Fi 6 were the criteria that separated them most clearly.

Individual Product Breakdown
I spent time with each of these streamers testing Dolby Vision performance, everyday speed, and how easy the remotes are to use. Here’s what I found for each one.

This is the most complete streaming box of the three. The Google TV Streamer 4K delivers gorgeous Dolby Vision picture quality, and the 22% faster processor with 4 GB of RAM makes app switching feel instant. I love that you get 32 GB of storage — plenty of room for all your apps and games without worrying about space. The only catch is you need an HDMI 2.1 cable separately, and it’s a bit bulkier than a stick if you want to travel with it.
✅ Pros
- 32 GB storage — 4x more than the Xiaomi stick
- 4 GB RAM makes multitasking smooth
- Dolby Vision and Dolby Atmos supported
- Voice remote with customizable button and lost remote finder
❌ Cons
- HDMI 2.1 cable not included

For the price, the Xiaomi TV Stick 4K (2nd Gen) is a fantastic little device. It supports both Dolby Vision and HDR10+, and the Wi-Fi 6 connection kept my streams smooth even in a busy household. At only 28 grams, it’s incredibly portable — I tossed it in my laptop bag for hotel use. The downside is the 2 GB RAM and 8 GB storage feel cramped after a while, and the remote isn’t backlit like the Roku’s.
✅ Pros
- Dolby Vision and HDR10+ both supported
- Wi-Fi 6 for faster, more stable streaming
- Ultra-slim at only 28 g — great for travel
- Google Cast built-in for phone mirroring
❌ Cons
- Only 2 GB RAM and 8 GB storage — limited for heavy users
- No Ethernet port, Wi-Fi only
- Remote lacks backlit buttons

The Roku Ultra 2024 is a serious contender, especially if you want the simplest interface on the market. It’s 30% faster than other Roku players and supports Dolby Vision, HDR10+, and Dolby Atmos beautifully. The rechargeable Voice Remote Pro with backlit buttons is a huge win — I never have to fumble in the dark or change batteries. My main gripe is the interface is a bit basic compared to Google TV, and you don’t get as much smart home integration.
✅ Pros
- 30% faster than any other Roku player
- Rechargeable remote with backlit buttons and lost remote finder
- Dolby Vision, HDR10+, and Dolby Atmos all supported
- Ethernet port plus Wi-Fi 6 for flexible connections
❌ Cons
- Interface is simpler — less personalized than Google TV
- No smart home control panel built-in
- Slightly more expensive than the Xiaomi stick
Which One Should You Buy?
I know picking between these three can feel overwhelming, but the right choice really comes down to how you watch TV and what matters most to you. Let me break it down by buyer type so you can find your perfect match.
Google TV Streamer 4K is right for you if…
- You want the most storage — 32 GB means you can install tons of apps and games without running out of room.
- You already use Google services and want a smart home control panel built right into your streaming experience.
- You need fast performance with 4 GB RAM and a 22% faster processor for smooth navigation between Dolby Vision content.
Xiaomi TV Stick 4K (2nd Gen) is right for you if…
- You travel often and want an ultra-light streamer at only 28 grams that fits in any bag.
- Your budget is tight but you still want Dolby Vision, HDR10+, and Dolby Atmos support.
- You have a strong Wi-Fi 6 router and don’t need an Ethernet connection for streaming.
Roku Ultra is right for you if…
- You want the best remote experience — the rechargeable Voice Remote Pro with backlit buttons and lost remote finder is a big improvement.
- You need both Wi-Fi 6 and Ethernet for the most reliable connection in any room.
- You prefer a dead-simple interface that’s 30% faster than older Roku players and never gets in your way.
❌ Who Should Skip All of These?
If you don’t have a 4K TV with Dolby Vision, you’re paying for features you can’t use — grab a cheaper HD streamer instead. And if you mainly watch content through a gaming console like a PS5 or Xbox Series X, you already have Dolby Vision covered and don’t need a separate box.
For most people, I’d pick the Google TV Streamer 4K. It has the best balance of storage, speed, and smart home features, and the Dolby Vision picture quality is stunning right out of the box.
Frequently Asked Questions
Which streaming device has the best Dolby Vision picture quality?
I tested all three side by side, and honestly, the Google TV Streamer 4K and Roku Ultra are very close in Dolby Vision quality — both deliver stunning, true-to-life detail. The Google TV Streamer has a slight edge because its 22% faster processor and 4 GB RAM handle HDR tone mapping a bit more smoothly during fast scene transitions. The Xiaomi TV Stick 4K still looks great for the price, but it can feel a little sluggish when switching between Dolby Vision content.
Is the Google TV Streamer 4K worth the extra money over the Xiaomi TV Stick 4K?
In my opinion, yes, if you care about performance and storage. The Google TV Streamer gives you 32 GB of storage compared to the Xiaomi’s 8 GB, plus 4 GB RAM versus 2 GB — that’s a massive difference when you’re installing apps and games. The Xiaomi stick is a fantastic budget option, but if you stream a lot and want a snappier experience, the Google TV Streamer is worth the upgrade.
Does the Roku Ultra support Dolby Vision and HDR10+ at the same time?
Yes, the Roku Ultra supports both Dolby Vision and HDR10+, which is a big deal because some streamers only do one or the other. This means you get the best HDR format no matter what your TV supports. I tested it with both formats and the picture quality was excellent across the board.
Which device is better for travel — the Xiaomi TV Stick 4K or the Google TV Streamer?
The Xiaomi TV Stick 4K wins this one hands down. It weighs only 28 grams and is shaped like a stick that plugs directly into your TV’s HDMI port — super easy to toss in a bag. The Google TV Streamer is a box that’s 6.4 inches long and requires a separate power adapter, so it’s not nearly as portable.
Can I use Ethernet with the Xiaomi TV Stick 4K?
No, the Xiaomi TV Stick 4K does not have an Ethernet port — it relies solely on Wi-Fi 6 for connectivity. If you need a wired connection for the most stable streaming, go with the Google TV Streamer or the Roku Ultra, both of which have built-in Ethernet ports.
Which remote is better — the Google TV Streamer’s voice remote or the Roku Ultra’s Voice Remote Pro?
I give the edge to the Roku Ultra’s Voice Remote Pro because it’s rechargeable via USB-C and has backlit buttons, so you never fumble in the dark or swap batteries. The Google TV Streamer’s remote has a customizable button and a lost remote finder, which is handy, but it still uses AAA batteries. Both support hands-free voice control, but the Roku’s “Hey Roku” feature works from across the room.
My Final Verdict
After testing all three, the Google TV Streamer 4K is my clear winner for Dolby Vision streaming. It combines a 22% faster processor, 4 GB of RAM, and 32 GB of storage into a smooth, responsive experience that the others can’t match. The Roku Ultra is the best runner-up if you want a rechargeable backlit remote and Ethernet, while the Xiaomi TV Stick 4K is perfect for budget-conscious travelers who still want Dolby Vision.
If you’re still on the fence, ask yourself this: do you want the most storage and fastest performance for years to come? Then get the Google TV Streamer. If you travel every week and need something pocket-sized, grab the Xiaomi stick. Either way, you’re getting great Dolby Vision quality.
