Keychron C3 Pro vs Lemokey X18K Polling Rate vs Budget Tray Mount

The core differences are the polling rate and mounting style. The C3 Pro features a configurable 8000Hz polling rate and a gasket mount, while the X1 has a 1000Hz polling rate and a tray mount. The C3 Pro also uses PBT keycaps and full RGB, whereas the X1 uses ABS keycaps and red backlighting.
