What will you mostly use it for?
The K10 V2 is the more straightforward fit for desk work that benefits from a numpad, function row, and multimedia keys. The KM40 is the clear portability choice, with a smaller 40% format, lower listed weight, and an additional 2.4 GHz connection option. Programming and modding are close calls because both boards support hot-swapping and QMK/VIA, though the KM40 offers an explicitly described multi-layer layout. For content creation, the K10 V2's full-size key coverage is likely more practical if dedicated keys matter.
