Compare Keychron K8 QMK V2 vs Q3 Differences Side by Side

This comparison is for mechanical keyboard enthusiasts deciding between two 80% TKL keyboards from Keychron. Both offer QMK/VIA support and hot-swappable switches, but they serve very different priorities. The K8 QMK V2 is built for flexibility with a wireless Bluetooth connection and a lighter ABS frame, while the Q3 is a wired-only, heavy-duty keyboard with a full CNC aluminum chassis and a double-gasket design. The decision is hard because both are excellent customizers, but your need for mobility versus a premium fixed desk setup will be the deciding factor.
