Our Verdict

AULA F99/F75

Keychron K8 Max [K2 Max, K10 Max, etc.]

The AULA F75 and the Keychron K8 Max are wireless mechanical keyboards. They're quite similar in their overall feature set, but the Keychron has noticeably better build quality with a higher-quality material feel and an option for a much more sturdy-feeling aluminum bracket frame. They both offer excellent typing experiences, but the AULA has a much softer and very springy gasket-mount design, while the Keychron has a much stiffer and more traditional tray-mount design. Neither is better in this respect, it only comes down to your typing preference.
