Keychron Q6 [Q1, Q3, etc.] Ultra vs K2 [K4, K8, K10, etc.] Ultra 8K

Both the Keychron Q6 [Q1, Q3, etc.] Ultra 8K and the Keychron K2 [K4, K8, K10, etc.] Ultra 8K are lineups of wireless mechanical keyboards with excellent typing quality. The main differences are in their construction and typing feel. The Q Ultra boards have fully aluminum cases, polycarbonate plates, and double-gasket mounting for a softer, more cushioned typing feel. The K Ultra boards have aluminum frames but ABS plastic undersides and steel plates, providing a firmer typing feel. They also have OSA-profile keycaps, which have a fairly tall shape and rounded edges, while the Q Ultra boards have slightly taller KSA-profile keycaps with more deeply sculpted tops.
