Compare Keychron K4 Pro vs R5 Differences Side by Side

This comparison is for buyers looking at two 96% Keychron wireless keyboards that share a similar compact layout but differ in connectivity and customization depth. The decision is hard because both offer hot-swappable switches, PBT keycaps, and QMK support, yet each serves a different primary use case. The K4 Pro is better suited for programmers and modders who want VIA support and multiple layout options, while the R5 is a better fit for users who prioritize low-latency wireless via 2.4 GHz. Neither keyboard is a clear winner across the board, so the right choice depends on whether you value firmware flexibility or connection speed.
