Our Verdict

Logitech MX Keys S

NuPhy Air75 V3

The Logitech MX Keys S and the NuPhy Air75 V3 are low-profile keyboards mainly targeted at office workers. While Logitech benefits from the inclusion of shine-through keycaps and a very quiet and comfortable typing experience, the NuPhy's mechanical switches are more satisfying to type on. The latter also delivers much better latency performance and a more robust software experience.
