Choose the Keychron K4 Pro if programmable layouts, documented QMK/VIA support, ISO availability, or its listed 1000 Hz polling rate are the deciding factors. Choose the Royal Kludge RK96 if you specifically want 2.4 GHz wireless, USB pass-through ports, or an included wrist rest. Both retain the 96% layout and hot-swappable switches, so the main trade-off is customization and layout flexibility versus desk features and connectivity options.

What will you mostly use it for?
The K4 Pro takes the lead for programming, modding, and content creation because its QMK/VIA support provides more clearly documented customization options. Its listed polling rate also gives it the edge for gaming, though the RK96 adds a 2.4 GHz connection option. Office users may prefer the K4 Pro's multi-device Bluetooth switching or the RK96's wrist rest and pass-through ports. For travel, the K4 Pro is lighter in the comparison metadata, while the RK96 offers an extra wireless mode, so priorities matter.

- The K4 Pro lists a 1000 Hz polling rate.

Keychron K4 Pro vs Royal Kludge RK96: your questions
The K4 Pro has QMK and VIA support, and Keychron describes key remapping and macro creation through its Launcher web app. The RK96 also has customization software, but its vendor says the programmer is for Windows and wired mode.
