Compare Keychron J2 HE vs J8 HE Differences Side by Side

This comparison is for buyers deciding between two wired 75% keyboards from Keychron that share many core features: 8000 Hz polling, Hall Effect magnetic switches, and Cherry profile PBT keycaps. The decision is hard because both offer similar performance and customizability through the Launcher web app. The main differentiators are the presence of a multi-function knob and included Mac keycaps on the J8 HE versus the lower weight and lower price of the J2 HE. One user review for the J2 HE reports a defect, so that should be weighed when choosing.
