NuPhy Air75 V2 [Air60 V2, Air96 V2] vs NuPhy Nos75

The NuPhy Air75 V2 and the NuPhy Nos75 are low-profile mechanical keyboards. On the one hand, the Air75 is a bit thinner. It also has wireless connectivity and offers several switch options at purchase. It also has both a slightly smaller  60% and slightly larger 96% variant available. The Nos75 is a slightly thicker wired-only model. It has a much more premium-feeling build quality with a solid aluminum case design and more of a focus on hardware customizability with several options for different gasket mount systems. It also has significantly better typing quality overall, but it's only compatible with the Gateron N1 Nano switches it comes with. Unfortunately, the Nos75 has been discontinued and is no longer available for purchase new from NuPhy.
