This comparison is for buyers choosing between a compact, wired TKL keyboard and a larger keyboard with wireless and wired connectivity. The C1 Pro lists 8000 Hz polling, while the K4 Pro pairs a 96% layout with a 4000 mAh battery and Bluetooth. Both support hot-swapping, QMK, VIA, RGB lighting, and multiple switch types. The choice depends mainly on whether wired responsiveness and a smaller footprint or wireless flexibility and a more expansive layout matter more.

Choose the C1 Pro if you want a wired TKL board and value its listed 8000 Hz polling option. Choose the K4 Pro if wireless connectivity, multi-device use, or a number pad matters more than minimizing weight and size. Both offer hot-swapping and QMK/VIA support, so layout and connection preference are the main deciding factors.
The C1 Pro has the clearest gaming advantage on paper because it lists an 8000 Hz polling option and uses a wired connection. The K4 Pro suits office use where wireless connectivity and switching among devices are useful, and it also offers the larger layout for numeric work. Programming is a close call because both support QMK, VIA, and hot-swappable switches, with layout preference deciding the fit. For travel, the C1 Pro is lighter and smaller, while the K4 Pro avoids a required cable but weighs more.
