Verdict

Keychron K3 Pro

8 / 10 Expert Rating

A genuinely slim mechanical board that keeps real hot-swap switches and open QMK/VIA programmability rather than trading them away for thinness.

Leopold FC900R

8 / 10 Expert Rating

A no-frills, exceptionally well-built full-size board for typists who care more about switch feel than RGB or features.
