What will you mostly use it for?
The B75 Pro Max is the stronger fit across these use cases when screen functionality, configurable controls or QMK/VIA matter. The C75’s clearest distinctions are its aluminum case and listed 1000 Hz polling rate, which may appeal to shoppers prioritizing those specifications. For travel, the B75 Pro Max has the larger battery and is slightly smaller and lighter by the listed measurements. Both use south-facing LEDs, so keycap lighting compatibility is a shared consideration.
