What will you mostly use it for?
The V10 Ultra has the clearer advantage for gaming, broad switch experimentation, and workflows that could benefit from a knob. The K15 Max is the more compelling choice for buyers who specifically want a low-profile Alice keyboard, QMK, or a lighter board to carry. Both offer wireless and wired connections, hot-swap functionality, RGB, and remapping through Keychron Launcher. Office and programming preferences may depend more on whether low-profile typing or the V10 Ultra's normal-profile design and knob suit your setup.
Pick the Keychron V10 Ultra
- The V10 Ultra supports 8000 Hz polling in wired and 2.4 GHz modes, compared with the K15 Max's 1000 Hz.
- Both offer 2.4 GHz, wired, and Bluetooth connections, plus N-key rollover.
