It's not my area of specialisation, but I watch developments with interest. I think most people still consider Maya the ultimate for rigging, but I don't think Cinema is doing too badly in that department either. We recently improved quite a lot about weights and symmetry workflows, and before that Character Object and C-Motion were good leaps forward in setting up these things quite quickly without a great deal of in-depth knowledge...
I found Noseman's recent 4 hour rigging series on the Maxon training team's YT channel particularly helpful in understanding all the rigging basics and possibilities open to us, so maybe it would help you catch up too...
Or for even more detail, and a better focus on character rather than than machine riggings, there was this excellent (and exhaustively thorough) series that preceded it.
