#2 The major difference between WWE and its competition

Triple H also mentioned how WWE helps Indy Stars grow and reach the next level in professional wrestling.
One of the main differences between WWE and its competition is the fact that the former delves more into the 'entertainment' aspect of the business to a point where the superstar with the best personality is more likely to succeed than a superstar with the best wrestling skills but zero personality on camera.
Triple H also listed some examples like Finn Balor and Ricochet, who knew everything about wrestling but were also slightly overwhelmed when it came to presenting themselves on camera.
Therefore, Triple H views non-WWE territories as a means to perfect the in-ring craft of Professional Wrestling. However, WWE strives to be much more than that. Entertainment and characters are a huge part of WWE's success.
With that said, if AEW looks to serve as a legitimate alternative to WWE, then the former has to tap into the 'entertainment' aspect of the business, otherwise we already have many promotions which offer top-notch in-ring product.
