What will you mostly use it for?
The C3 HE is the stronger fit for gaming features and workflows that benefit from a full-size layout. The K2 Max takes office and travel use when wireless operation or a smaller footprint is the priority. Programming is a close call because both support QMK, VIA, and hot-swappable switches, but their layouts differ. The K2 Max is the more flexible starting point for switch and keycap changes, subject to its south-facing LED caveat.

- The C3 HE has Hall Effect switches, adjustable actuation, Rapid Trigger, Dynamic Keystrokes, and Analog Mode.
