Choose the K5 Ultra if you want the low-profile 100% layout, a numpad, and its 8000 Hz polling, features the P1 HE does not offer. Choose the P1 HE if adjustable Hall Effect actuation, Rapid Trigger, a gasket mount, and a full metal case matter more than a numpad or low-profile design. Check the switch and keycap restrictions before buying either board.

What will you mostly use it for?
The P1 HE is the more specialized gaming and modding pick, with magnetic-switch controls, Rapid Trigger, and a gasket-mounted metal build. The K5 Ultra is a stronger fit for buyers who need a numpad, want a lighter low-profile board, or prioritize its listed 8000 Hz polling. Programming and content creation depend more on whether compact programmable controls or a full-size layout better fits the workflow. For travel, the K5 Ultra's listed weight is lower, though both boards support wireless use.

Keychron K5 Ultra vs LemoKey P1 HE: your questions
The P1 HE is the more specialized choice for adjustable key behavior, with Hall Effect switches, adjustable actuation, Rapid Trigger, and analog mode. The K5 Ultra lists 8000 Hz polling in wired and 2.4 GHz modes, compared with the P1 HE's listed 1000 Hz in those modes.
Yes, the P1 HE lists Rapid Trigger and its product description calls it dynamic Rapid Trigger. The description says keys can activate or deactivate based on travel distance rather than fixed points.
No, the P1 HE is specified for Gateron Double-Rail Magnetic switches only. Standard MX switches will not fit its magnetic-switch sockets.
The K5 Ultra requires low-profile switches and keycaps, so standard MX keycaps will not fit. Its north-facing LEDs may also interfere with Cherry-profile keycaps.

The K5 Ultra has a 100% layout, a numpad, and a low-profile design. The P1 HE is a 75% board without a numpad, though it has a gasket mount and programmable knob and macro-column controls.
The K5 Ultra lists ANSI and several ISO layouts, including ISO-FR, ISO-ES, and ISO-IT. The P1 HE compatibility information excludes ISO-FR, ISO-ES, and ISO-IT.
