Our Verdict

Keychron K3

NuPhy Air75

The Keychron K3 and the NuPhy Air75 are both compact, low-profile mechanical keyboards intended for different uses. The Keychron is better suited for office use, whereas the Nuphy is better for gaming since it has better latency, and every key is macro-programmable. Also, it uses PBT keycaps rather than ABS. On the other hand, the key legends on the Keychron are shine-through, so you'll be about to see your keys in the dark. The NuPhy is hot-swappable, and the Keychron also comes in a hot-swappable variant, so you can change out the stock switches without soldering.
