What will you mostly use it for?
The K2 HE is the gaming-focused pick for buyers who want magnetic-switch behavior and adjustable actuation, though the V3 Ultra has the higher polling rate. The V3 Ultra gets the edge for programming, modding, travel, and content creation, mainly through conventional MX-style switch compatibility, lower listed weight, and per-key lighting controls. Office use is close because both offer wireless connections, a knob, and sound dampening. Battery-life figures favor the V3 Ultra when its backlight is off.

“Lowering the actuation depth improved my reaction time in competitive games. Analog mode in racing titles feels surprisingly natural. The mouse glide is smooth.”
“I thought the macro didn't have infinite repetitions, but there are no helpful images anywhere on the internet. I still haven't found the answer.”

“Second Keyboard I buy from Keychron! I live in El Salvador and it arrived on time and perfectly. Extremely comfortable, outstanding switches. Best keyboard I've had in my life.”
