Agreed with Tom. Basically...
It depends on which level/version each character is in.
Each character has feats the others don't, others have stalmated each other in battles, then add on the fact all their character info labels each of them as "Class 100+ Strength" or "Incalculable".....all things making it even harder to determine who exactly is above who.
If we're being fair, taking bias out of it, considering best and worst feats, and using characters at their BASE level....
I say their all even....🤷🏾♂️
