What will you mostly use it for?
The V3 is the more suitable pick when gaming or programming calls for a complete keyboard, and its QMK/VIA support gives it an edge for customization. The AL21 stands out for travel and for adding wireless numeric input to an existing setup. Office and content-creation needs depend on whether a full keyboard or a compact keypad and knob better fits the desk workflow. These boards serve different roles, so layout is the main deciding factor.
Pick the Keychron V3
- The V3 is an 80% keyboard, while the AL21 is a 19-key numpad rather than a full keyboard.
- The V3 lists a 1000 Hz polling rate and supports linear, tactile, and clicky switches.
- The AL21 supports N-Key Rollover, but its numpad layout limits it to supplementary input.
