The Amazon Fire TV Cube costs $139. The Roku Streaming Stick 4K costs $49. The $90 gap raises a legitimate question: can a mid-range stick deliver the same streaming experience as Amazon's flagship device? For content quality, mostly yes. For hands-free Alexa and HDMI-in integration, no.

The $90 Difference: What It Buys
Hands-free Alexa: The Cube's built-in microphones respond to "Alexa" without touching the remote. The Roku Streaming Stick 4K requires pressing the voice button.
HDMI-in: The Cube can integrate a cable or satellite box — route it through the Cube and control everything with Alexa. The Roku Stick has no HDMI-in.
Ethernet: The Cube ships with wired connectivity; the Roku Stick is Wi-Fi only.
Wi-Fi 6E: The Cube's 6GHz support is ahead of the Stick's Wi-Fi 6.
These are genuine features. But they're only meaningful for households with Alexa setups or cable box integration needs.
For Streaming Content: Minimal Difference
Both deliver 4K Dolby Vision and Dolby Atmos to your TV. Netflix on a Roku Streaming Stick 4K looks the same as Netflix on a Fire TV Cube. The $90 premium doesn't upgrade the content.
Platform Choice
The Roku Streaming Stick 4K's neutral platform is a meaningful advantage for households without a dominant ecosystem. No Amazon promotion, no Google promotion — equal treatment for every app. The Roku app catalog is also the widest available.
The Fire TV Cube rewards Amazon subscribers. Prime Video at best quality, Alexa integration, and Amazon ecosystem features all work naturally.
