Score: 83/100Rankings

The Zidoo Z20 PRO is a premium 4K HDR media player featuring a Realtek quad-core processor, dual HDMI outputs and an internal SATA bay supporting up to 16 TB of storage. Its high price and limited USB 3.0 connectivity may deter budget-focused buyers. Ideal for home-theater enthusiasts seeking cinema-grade video and extensive local storage.

The RockTek GX1 is an ultra-compact Google TV 12 set-top box that offers 4K UHD streaming with Dolby Vision, HDR10+ and Dolby Atmos, powered by a Realtek RTD1325TPV processor and 4 GB RAM. Its limitations include a 100 Mbps Ethernet port, lack of VC-1 support, and USB 2.0 only. It is best for users who value a tiny footprint, Wi-Fi 6 performance and premium HDR video in a budget-friendly package.

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

Professional reviewers regard the Z20 PRO as a premium home-theater solution, highlighting its flawless 4K@60Hz HDR playback, robust build quality, powerful processor, and expansive storage options, while noting its high price and potential chassis discoloration as the main 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.
