Products in the top-left offer the best value (high score, low price).

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.

Professional reviewers praise the Minix U8K-Ultra for its rock-solid 8K@60 Hz playback, powerful hexa-core processor, and advanced AI upscaling, but note its lack of full Android TV certification and higher price.
Everyday users love the stunning 8K HDR picture quality, fast performance, and expandable storage, but are frustrated by SD-only streaming on popular services and the premium price tag.
