Our Verdict
Keychron K2 HE [K4 HE, K8 HE, etc.]
NuPhy Halo65 HE
The Keychron K2 HE and the NuPhy Halo65 HE are both keyboards with Hall effect switches. The Keychron K2 HE has a 75% layout with a dedicated function row, arrow keys, and a cluster of navigation keys, making it more versatile for productivity tasks without sacrificing too much desk space. It also offers wireless connectivity, which the NuPhy lacks. On the other hand, the NuPhy has better raw performance with a maximum polling rate of 8000Hz. It also has a more robust set of adjustable actuation features and a wraparound RGB lighting strip, which the Keychron lacks.
