The biggest difference between these companies right now is that WWE can bring anyone in and protect them / train them to have a good match. Logan Paul, Shane, Bad Bunny, Pat McAfee, Ronda, Dom, et cetera. But they abuse this power to the point where thats most of what theyre featuring now.

Meanwhile if AEW wants to train you they have QT Marshall showing you the ropes lol. So they have to pirate the indies / japan whenever they need a new hand
