Choose the Jamesdonkey R3 HE if its 8000 Hz polling, TMR sensor, and smaller 65% layout matter more than wireless use or programming options. Choose the Keychron LemoKey P1 HE for Bluetooth and 2.4 GHz connectivity, ISO layouts, QMK and VIA support, and a customizable knob. Both are limited to magnetic switches, so standard MX switch compatibility is not a reason to choose either one.

What will you mostly use it for?
The R3 HE is the more gaming-focused pick here, especially for buyers prioritizing its higher listed polling rate and compact layout. The P1 HE has the edge for office work, programming, modding, and content-creation setups that can make use of wireless modes, layout options, and its knob. Travel is a trade-off: the R3 HE is smaller and lighter, while the P1 HE can operate wirelessly. Both keyboards require magnetic switches, so neither suits buyers planning to use standard MX switches.
Pick the Jamesdonkey R3 HE
- Its listed polling rate is 8000 Hz, compared with 1000 Hz for the Keychron in wired and 2.4 GHz modes.
- The vendor describes the R3 HE's Rapid Trigger accuracy as 0.01 mm.
- Its 65% layout gives it a smaller footprint than the Keychron's 75% layout.
