What will you mostly use it for?
The QK108 is the stronger fit when a numpad or stated VIA/QMK support matters, while the RT75 suits buyers who want a smaller layout and a screen with specified display options. Both offer three connection modes and hot-swappable construction, so office use can reasonably go either way. The RT75 is more compact by layout and dimensions, but its battery capacity is lower. For customization, the choice is between the QK108's remapping support and the RT75's detachable display module.
Pick the Epomaker QK108
- Both list 1000Hz polling over wired or 2.4GHz connections.
- The QK108 has N-Key Rollover and VIA support, which the RT75 listing does not specify.
- The RT75's 75% layout is an option for buyers who prefer fewer keys.
