Select the Ajazz AK820 Pro if you want a practical layout with a unique screen and strong wireless performance for general use and gaming. Opt for the Yunzii AL66 if you prioritize a premium all-metal build, extensive sound modding potential, and the most compact form factor, and are willing to adapt to a 65% layout. Your choice fundamentally comes down to layout utility versus material quality.
The Ajazz AK820 Pro wins for tasks requiring more direct key access, like office work, programming, and gaming, thanks to its 75% layout and screen. The Yunzii AL66 is better for travel due to its smaller size and larger battery, and for modding due to its detailed foam kit and aluminum build. For content creation, the knob and wireless features make both equally viable.
