Pros and Trade-offs

Choose the Keychron V5 QMK if you prioritize compact desk space, deep QMK-based programmability, and a straightforward modding platform. Go with the Keychron V6 Ultra if you need wireless connectivity, the fastest polling rate, a full-size numpad for productivity, and a more refined typing experience with gasket mounting and acoustic foam. Your final decision should hinge on whether wireless freedom and a full layout or compact size and open-source firmware matter more to you.

Keychron V5 QMK

+QMK firmware offers extensive open-source programmability for key remapping and macros.
+96% layout (1800 compact) saves desk space while retaining a full numpad and function row.
+Steel plate provides a stiff typing feel with a solid, consistent keypress.
+Tray mount design is a well-known and straightforward platform for modifications.

−Wired-only connectivity limits desk setup flexibility and portability.
−1000 Hz polling rate is lower than the V6 Ultra's 8000 Hz, potentially impacting competitive latency.
−ABS plastic case and tray mount may produce more acoustic resonance without added foam layers.

Keychron V6 Ultra

+8K Hz polling rate in both wired and 2.4 GHz wireless modes for extremely low input lag.
+Full 100% layout includes a complete numpad and dedicated navigation cluster.
+Wireless connectivity with 2.4 GHz and Bluetooth 5.3 supports up to three devices.
+Large 4000mAh battery offers up to 660 hours of use (backlight off).
+Gasket mount design with PC plate and multiple acoustic foam layers (EPDM, PET) for a quieter, softer typing feel.

−Uses ZMK firmware instead of QMK, which may feel less familiar to users accustomed to QMK's ecosystem.
−Larger 100% footprint takes up more desk space than the V5 QMK's compact 96% layout.
−Heavier and larger form factor makes it less portable than smaller keyboards.
