What will you mostly use it for?
The C4 HE wins decisively for gaming and content creation due to its 8000 Hz polling and Hall Effect switches, and it also leads for modding thanks to its gasket mount and QMK/VIA support. The K4 V2 takes the office and travel categories with its Bluetooth 5.1 connectivity and large battery. For programming, they tie because both offer a number pad and hot-swappable switches without a clear advantage in firmware customization based on available data.
Pick the Keychron C4 HE

- Hall Effect magnetic switches enable adjustable actuation points for responsive gaming control

Keychron C4 HE vs K4 V2: your questions
