Quick Comparison

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.
