MJF is a more versatile character than Roman Reigns
Roman Reigns has been a must-see star simply because of how good he is as the Head of the Table. But MJF has shown his greatness in multiple characters throughout his AEW run.
Early on, he was a babyface and a friend of Cody Rhodes. Although most people knew that MJF would eventually turn on The American Nightmare, the turn and the subsequent feud was amazing. Similarly, as the goofy heel in Inner Circle, MJF showed a more comical side of his character. He then single-handedly turned the Inner Circle babyface through his betrayal of the group.

Many fans still remember how Reigns' babyface run was underwhelming due to WWE's questionable booking. This period of The Big Dog's career exposed some of the shortcomings in his ability to be a versatile character, though he's currently thriving as a heel. As a result, MJF wins this round of comparison, too.
MJF feels like a natural heel, and Roman Reigns seems manufactured
Roman Reigns is a WWE product. In a few years, he could easily be a megastar in Hollywood, but for now, he continues to battle a negative perception. Many fans look at him as a star who was borne out of the way a multi-billion dollar company pushed one guy for nearly a decade.
MJF, on the other hand, feels like a more organic character who is genuinely a disrespectful jerk. The fact that he never breaks character helps him seem even more genuine. Moreover, MJF has stated that he will go where the money lies once his AEW contract expires.
Nobody knows if this claim is a work or a genuine preview of the future, and it's this blurring of lines that makes MJF come across as the superior heel. His villanous antics aren't limited to other wrestlers; in his promos, he hints that he's willing to turn on his own company by leaving it for the competition. This decision would be the biggest heel move any wrestler could possibly make.
