Same Wi-Fi, Different Ecosystems
Both devices use Wi-Fi 5 — so connectivity is equivalent. Both stream 4K content from all major services. The comparison is entirely about platform.
Dolby Vision: The Fire TV Stick 4K supports Dolby Vision; the Roku Express 4K+ does not. This is the most meaningful spec difference: on a Dolby Vision TV, the Fire Stick produces better HDR.
Alexa vs. Roku Voice: The Stick 4K integrates with Alexa for smart home control. Roku Voice handles streaming search but not smart home.
Platform: Roku is neutral; Amazon promotes Prime Video on the home screen.
Price: Roku Express 4K+ is $10 less.
Who Should Choose Which

- You use Alexa for smart home control
Get Roku Express 4K+ if:
- You want a neutral platform with no ecosystem pushing
- $39 is the right budget
- Your TV doesn't support Dolby Vision (the HDR difference disappears)
