The Roku Ultra costs ~$99. The Amazon Fire TV Stick 4K costs ~$49. Both deliver 4K Dolby Vision streaming. The Roku Ultra is Roku's flagship; the Fire TV Stick 4K is Amazon's capable budget option. Does the Roku Ultra's $50 premium buy enough to justify it?
Quick Comparison
What the Extra $50 Buys
The Roku Ultra's $50 premium over the Fire TV Stick 4K buys specific, tangible features:
Ethernet: The Roku Ultra ships with a built-in Ethernet port. Wired connections eliminate Wi-Fi buffering and provide consistent throughput. For 4K HDR streams on congested home networks, Ethernet is a meaningful stability upgrade. The Fire TV Stick 4K has no Ethernet option.
Remote headphone jack: The Roku Ultra remote has a 3.5mm headphone jack for private listening — plug in any headphones and audio routes directly from the remote. This is one of the most underrated features in streaming hardware. Late-night viewing without disturbing others becomes effortless.
Lost remote finder: Press a button on the Roku TV interface and the Ultra remote chirps. A minor feature with outsized day-to-day value if you regularly lose remotes.
Wi-Fi 6 vs. Wi-Fi 5: The Roku Ultra connects on modern Wi-Fi 6 networks; the Fire TV Stick 4K is limited to Wi-Fi 5.
Platform neutrality: Roku's home screen treats every streaming service equally. The Fire Stick 4K promotes Amazon content on its home screen.
Streaming Quality: Identical for the Content
Both stream 4K at 60fps with Dolby Vision and Dolby Atmos. Netflix on the Roku Ultra looks the same as Netflix on the Fire TV Stick 4K. The Roku Ultra's Ethernet advantage matters for network stability, not visual quality.
Ecosystems
Roku Ultra's neutrality is a genuine advantage for households without a dominant ecosystem. If you split time across Netflix, Disney+, HBO Max, and Tubi with no particular loyalty to Amazon or Google, Roku is the cleanest experience.
The Fire TV Stick 4K is the better device if you're a Prime Video subscriber — Amazon streams its own content at highest quality on its own hardware, and Alexa integration with the rest of your home works naturally.
Our Picks
Bottom Line
The Roku Ultra's $50 premium is worth it if you want Ethernet for rock-solid wired streaming, value the remote headphone jack for private listening, or want a neutral platform for a multi-service household.
The Fire TV Stick 4K is the right call if you subscribe to Prime Video, use Alexa in your home, and don't need Ethernet. At $49, it's excellent value for Amazon ecosystem users.
For the primary TV in a home with a wired connection available: Roku Ultra. For secondary TVs, budget builds, or Amazon-first households: Fire TV Stick 4K.
