What will you mostly use it for?
The P1 HE takes the edge in gaming, office use, programming, modding, and content creation, mainly through its knob, gasket mount, and expanded magnetic actuation range. The K3 HE is the more travel-oriented option because its listed weight is much lower and its design is low-profile. Both share wireless and wired connection options, 75% layouts, and core Hall Effect gaming features. Layout availability may also settle the choice for buyers who need ISO-FR or ISO-ES.
