What will you mostly use it for?
The C3 HE has the clearest advantage for gaming, where its magnetic-switch controls add features beyond the X3’s shared wired connection and polling rate. For office use, its PBT keycaps are a concrete point of difference, though both offer full-size layouts and sound-dampening features. Programming and content creation are close matches because both provide full-size layouts and programmable keymaps. Neither is an obvious travel pick, and modders should weigh the C3 HE’s magnetic-switch limitation against the X3’s conventional mechanical switch options.
