The Sun Belt was always thought of as worse than C-USA, but by virtue of Coastal's recent rise along with App's and Louisiana's success, the Sun Belt has raised its profile. The conference just signed a contract with ESPN, better than anything CUSA has (I think they have contract with CBS Sports Network). FWIW, Board Favorite John Feinstein just wrote an article touting the success that Keith Gill has had as the Sun Belt commissioner. Gill played football at Duke, and worked for the NCAA, then at Vandy, OK, got the AD job at American University, and then was the assistant commissioner at the A-10 before getting the Sun Belt gig. Gill is the first African-American to get an FBS conference commissioner's job (Kevin Warren was the second), and he apparently has done well raising the profile of the conference:
