What will you mostly use it for?
The K1 Ultra is the more compelling fit for gaming and content creation if its 2.4 GHz connection, higher polling, or customizable knob matters to your workflow. For programming and modding, the V6's QMK and VIA support and wider layout selection give it a clear advantage. The V6 is also the lighter and smaller option for travel. Office use favors the Ultra's listed battery life, PBT keycaps, and acoustic foam, though the V6's lower weight may suit some desks and setups.

- The K1 Ultra lists 8000 Hz polling in wired and 2.4 GHz modes; the K1 V6 lists 1000 Hz.
- The Ultra adds 2.4 GHz wireless, while both keyboards also offer wired and Bluetooth connections.
