Cyborg was created as a team character. The solo push is a recent thing and it just takes a good writer/artist combo to give him a solo classic.
And on the real as far as comics he is if the same league as the rest you mentioned if not a class higher given his Justice League appearances since Rebirth and him being part of the classic New Teen Titans run in the 1980s
He fukking sucks breh. There are better black characters, including STATIC who should be getting burn
