Compare Keychron J2 HE vs Q1 V1 Differences Side by Side

This comparison is for buyers torn between two very different 75% keyboards from Keychron: the new J2 HE with cutting-edge magnetic switch technology, and the established Q1 V1 with its premium all-metal construction. The decision is hard because both are hot-swappable, gasket-mounted, and QMK/VIA compatible, but the J2 HE uses Hall Effect switches with adjustable actuation and an 8000Hz polling rate, while the Q1 V1 offers a full aluminum case, a programmable knob, and a mature modding ecosystem.
