What will you mostly use it for?
The K4 HE is the more practical fit for numpad-heavy office work and buyers seeking certain regional layouts. The P1 HE takes the lead for gaming-oriented customization, programming controls, and content workflows that can use a knob. For travel, the K4 HE is lighter, although the P1 HE is narrower. Modding favors the P1 HE’s listed barebones option, but both use magnetic-only switch compatibility.

- Both keyboards offer Hall Effect switches, adjustable actuation, and Rapid Trigger.
- The P1 HE adds Dynamic Keystrokes and a rotary knob with customizable functions.
- The P1 HE has a gasket mount and full-metal case.
