Choose the Keychron K3 V3 if QMK/VIA customization, N-Key Rollover, or ISO layout options matter more than a volume wheel or 2.4GHz wireless. Choose the Lofree Flow Lite if you want its gasket-mounted construction, three-mode connectivity, and aluminum volume roller. Both are restricted to low-profile switches and keycaps, and the K3 V3 also has a north-facing LED clearance consideration for Cherry-profile caps.

What will you mostly use it for?
The K3 V3 has the edge for gaming, programming, and modding based on its QMK/VIA features, N-Key Rollover, and multiple layout options. The Flow Lite leans toward office use with 2.4GHz wireless and a dedicated volume roller. Travel is a close call: the Flow Lite has the larger listed battery and more connection modes, while the K3 V3 is slightly lighter and its vendor describes multi-device Bluetooth. For content creation, choose based on whether key remapping or physical volume adjustment matters more.
Pick the Keychron K3 V3
