Verdict
Keychron K2 HE
8 / 10 Expert Rating
One of the only wireless Hall Effect boards on the market, and it doesn't meaningfully compromise the magnetic-switch feature set to get there.
Razer BlackWidow V4 X
7 / 10 Expert Rating
A solid, no-frills entry into Razer's ecosystem, but the lack of hot-swap sockets is a real limitation at this point in the market.
