What will you mostly use it for?
The J8 HE has an edge for office work, programming, and content creation, where its knob and system-specific keycaps offer useful controls. For magnetic-switch experimentation, its stated support for Gateron Jade gives it more options. The J2 HE is lighter, which may suit buyers carrying a keyboard, although both require a wired connection. Gaming is close on the listed polling rate and Hall Effect features, with different construction details separating the boards.
It's a tie
- Both list Hall Effect switches and an 8000 Hz polling rate.
- The J2 HE vendor description specifies adjustable actuation and a steel plate, while the J8 HE description specifies adjustable actuation and a multifunction knob.
