What will you mostly use it for?
The CK75 SE edges ahead for gaming, office use, travel, and content creation through its specified polling rate, screen, lighter listed weight, and vendor-described driver features. The CK75 is the more compelling fit for buyers who want a choice of linear or tactile switches and screw-in stabilizers. For switch replacement and hands-on modification, both have hot-swap support and 3-pin/5-pin compatibility stated by their vendors. Neither has an advantage for buyers who need shine-through legends, since both use south-facing LEDs.
