What will you mostly use it for?
The C4 HE has the clearer gaming advantage on listed polling rate and its Hall Effect magnetic switches. The Q6 leads for creative controls and switch-based customization, with a knob option and support for 3-pin and 5-pin MX switches. For office and programming, the Q6's controls and remapping features make it the more flexible pick. The C4 HE is lighter, but both remain wired full-size boards rather than compact travel keyboards.
Pick the Keychron C4 HE
- The C4 HE lists an 8000 Hz polling rate, compared with 1000 Hz for the Q6.
- Its vendor description identifies adjustable-actuation-point Keychron Ultra-fast Lime Magnetic switches.
