What will you mostly use it for?
The K1 V6 gets the edge for gaming and office use based on its higher vendor-listed wireless polling rate and larger battery. The K3 V3 is the more travel-oriented pick thanks to its smaller dimensions and lower weight. Programming is a close call because both offer QMK, VIA, and hot-swap support, with layout size the main distinction. For modding and content creation, the K3 V3's PBT keycap option and additional listed mount styles may matter more.
Pick the Keychron K1 V6
