What will you mostly use it for?
The K3 Max fits gaming, office work, programming, modding, and content creation more naturally because it is a complete 75% keyboard. Its VIA support and 12 multimedia keys also give it an edge for customization and desk-based tasks. The K0 Max is the travel pick when the goal is to add a separate numpad to an existing setup, and its knob and macro column offer dedicated controls. Neither product replaces the other if you specifically need its layout.
Pick the Keychron K3 Max
