Don’t think of boxing like the NFL, NBA, NHL and MLB.
Think of boxing more like television channels. Each has a different slate of programs, each claims to be the funniest, the best, the most popular, etc. Is one channel better than another? Who knows? Maybe you can have one comedy show fight another comedy show. But that proves only that Comedy A was better than Comedy B on that one day. Tomorrow, each channel will continue promoting its slate of shows to its own benefit.
