Our Verdict

GLORIOUS GMMK

Leopold FC900R

The GLORIOUS GMMK is better overall than the Leopold FC900R. The GLORIOUS has macro-programmable keys, RGB backlighting, and dedicated software. However, the Leopold offers a better overall typing experience with the Cherry MX Brown switches we tested, but they're each available in a range of switches, so your experience may vary.
