#4 Dean Ambrose was scripted, Jon Moxley is not
Often times it's easy to spot a scripted promo in WWE because it tends to have the same tone and message no matter who is delivering the promo.
Over the course of eight years, Dean Ambrose appeared in many scripted segments, including famous appearances on Miz TV, and delivering promos as a singles star and with The Shield.

The scripted nature of Dean Ambrose's promos were more often than not entertaining, as Ambrose is skilled enough to pull off a multitude of styles, but Jon Moxley is a different story.
Since leaving WWE, it's clear there has been a lot of pent up verbiage Moxley was unable to express in the scripted WWE environment, and he has been able to unleash more reality in his NJPW and AEW promos. Allowing Moxley to deliver his own promos has brought the audience closer to who Moxley is, and has shed new light on his in-ring persona.
