What will you mostly use it for?
The V1 Ultra has the clearer edge for gaming, modding, and workflows that benefit from a knob or detailed lighting controls.

Programming is a close match because both list QMK, VIA, hot-swap support, and Launcher access. For office use, the V1 Ultra's gasket mount and acoustic materials trade off against the K1 V6's lighter build.
