Our Verdict
GLORIOUS GMMK PRO
Keychron S Series
The GLORIOUS GMMK PRO and the Keychron S Series are wired mechanical keyboards with hot-swappable PCBs. The GLORIOUS is compatible with a much wider range of switch types and has lower latency, making it a better pick for gaming. On the other hand, the Keychrons have a low-profile design and feature robust software for customization. However, their hot-swappable PCBs are only compatible with Gateron Low Profile mechanical switches. It's important to note that the GLORIOUS is only available in a barebones version without pre-installed switches or keycaps, while the Keychron is a fully-assembled unit.
