What will you mostly use it for?
The Keychron Q3 Max wins in most productivity and customization-focused categories like Office, Programming, and Modding due to its extensive layout support, firmware options, and detailed acoustic construction. The Luminkey Lumino takes the lead for Travel thanks to its smaller dimensions. For Gaming, the Q3 Max's confirmed N-key rollover and gaming-focused marketing give it an edge. Content Creation is a tie, balancing the Lumino's visual screen against the Q3 Max's tactile knob.

“This is my first time trying "barebones". Im just blown away by the build quality. It is very heavy! But thats something i like about it, nothing you wanna carry around in a backpack on the train anyways. I picked up Gateron G Pro 3.0 Brown switches with it…”
