What will you mostly use it for?
The K1 V6 takes the edge for programming and modding because its QMK/VIA support is explicit, and it suits buyers who need ISO layouts. Its specified wired polling rate and broader switch choices also make it the more clearly documented option for gaming. The L75 is a stronger travel fit for shoppers who want 2.4 GHz wireless alongside Bluetooth and wired modes. For office and content creation, choose based on layout needs and the L75's extra wireless mode rather than assuming one layout suits everyone.
