I'd say the NWA (TNA) and WWF/E and the only ones I would consider true World Championships in the United States. ROH could get there at some point, but right now they're the highest-up of the many pretenders to the throne. The WCW Title, remember, was merged into the WWF title, and I believe the ECW was too. If not, I'll give ECW the benefit of the doubt, because nearly every casual fan knew what ECW was, as opposed to ROH or any other indie out there. I still have a hard time accepting the "World" Title, but the holders have done some good work legitamizing it, particularly Benoit, Orton, and Angle. If Rey comes out on top at WMXXII, that'll help its stock rise even further from "the belt HHH was handed while wearing a suit."
