What will you mostly use it for?
The B75 Pro has the clearest edge for gaming, office controls, programming layouts, modding options, and media-focused desk use, based on its polling rate, knob, ISO listing, and extra controls. The C75 is the more compelling travel pick on battery capacity and its stated multi-device switching, though its listed weight is higher. Both offer wireless and wired connectivity, hot-swappable switches, and a gasket mount, so those shared features do not decide the comparison. Choose by the features that matter most to your setup, especially layout, case material, and controls.
