What will you mostly use it for?
The K4 Max wins for gaming and office use due to its 2.4 GHz connectivity and built-in numpad. The K2 Pro excels for programming, travel, and modding because of its lighter weight, smaller footprint, and multiple mounting options. For content creation, both are equally capable thanks to shared QMK/VIA support and south-facing RGB. The choice ultimately depends on whether you prioritize a numpad and low-latency wireless or a portable, customizable compact board.
Pick the Keychron K4 Max

- K4 Max uses an ARM architecture MCU with 256KB flash, providing more flexibility for developer-level performance.
- Both keyboards have the same 1000 Hz polling rate in wired mode, but the K4 Max adds 2.4 GHz wireless for competitive play.
