Our Verdict

NuPhy Air75 HE

Logitech G515 RAPID TKL

The NuPhy Air75 HE and the Logitech G515 RAPID TKL are both low-profile keyboards that utilize magnetic switches. The NuPhy has a slightly more compact 75% layout, features a hot-swappable PCB, and offers switches with a noticeably longer travel distance. It also provides slightly better latency performance and superior build quality. Both models include features such as adjustable actuation and Rapid Trigger, but NuPhy's software is more comprehensive and accessible directly through a web interface.
