Impact has made a lot of bad business decisions. They were a legit #2 competitor to WWE at one point but after they started bringing in Hogan, Brischoff, over the hill talent, and became sketchy with business practices like not paying talent it been all down hill. ROH has a working relationship with NJPW. They don't have a "limited" ring style. Talent are allowed to work as they see fit. Impact has made strides in the passed year. They've established a working relationship with Lucha Underground and they have some nice talent there. Also you have to give Billy Corban credit for what he's done with NWA since buying it. They didn't even have a YouTube channel a year ago and have picked up a good amount of subs and rumors are they're going to be putting the title on Cody Rhodes at All In.
