Professional reviewers and editors consistently commend the Roku Ultra for its 30% faster processor, Wi-Fi 6 connectivity, and premium audiovisual support such as Dolby Vision and Dolby Atmos. They also highlight the feature-rich rechargeable Voice Remote Pro and the reliability of its wired Ethernet and local media playback options, positioning it as the most capable Roku device for high-end home-theater setups.
Everyday users praise the device's lightweight design, fast and responsive interface, and the convenience of the hands-free remote with a lost-finder. Stable streaming via Wi-Fi 6 or Ethernet and the ability to play local media are also frequently mentioned, while the higher price and lack of deep smart-home integration are noted as minor drawbacks.
Professional reviewers commend the GX1 for its striking Dolby Vision and HDR10+ performance at 2160p60, smooth AV1 playback, and the polished Google TV 12 experience. However, they point out the 100 Mbps Ethernet as a bottleneck for high-bitrate local streaming and note the absence of VC-1 support and limited ventilation as drawbacks for power users.
Everyday users overwhelmingly praise the GX1's video and audio quality, compact size, and responsive interface, often calling it a top-line product that outshines competitors. The most common complaints revolve around screen-resize issues on certain LCD TVs and the lack of Gigabit Ethernet for heavy NAS-based media consumption.
