Our Verdict
Keychron K2 HE [K4 HE, K8 HE, etc.]
NuPhy Air60 HE
The Keychron K2 HE and the NuPhy Air60 HE are analog gaming keyboards. The Keychron is a wireless model with a slightly larger form factor and a taller, standard profile. Comparatively, the NuPhy is a wired-only model. It has a thinner low-profile design and better raw performance with a maximum polling rate of 8000Hz.
