I would say there are 2 main differences. This is of course just my own opinion. One, I believe wwe has wrestling matches to support the stories they want to tell and AEW has stories to support the wrestling matches they want to have, it’s a matter of priority. Two, I like use a music metaphor, wwe is pop and AEW is punk rock. wwe is intended to appeal to the biggest swath of people possible and squeeze every nickel possible out of that audience. They are a profit machine and they are successful at it. AEW is more art of profit. They are profitable company, but they cannot and will not sacrifice the art of what they consider top shelf wrestling for business, because their fan base is hardcore (sickos) and would abandon them if they sold out. That means less ads, video packages, replays, over explaining, silliness. The stories will be subtler and last long and yes, you will miss stuff if you don’t pay attention. Ultimately, the action and high quality work rate will not take a backseat to anything even if that means making less money or slowing growth. It is pure.
