The B3 Pro weighs 410 g, while the C1 weighs about 685 g. That makes the B3 Pro the lighter option for moving between locations.
No, the B3 Pro is listed as having no RGB and the vendor describes it as non-backlit. The C1 has RGB-backlit variants, though its non-backlit version does not include lighting.
Neither has a numpad, according to their compatibility rules. The B3 Pro is a 75% layout, and the C1 is an 80% tenkeyless layout.
