Lol, I know you are just joking.
But in all seriousness in your thread
I personally have never read the gladiator comic.
But i just can guess that Thing should win the fight.
As per being the inspiration, that is a diferent subject.
Many of the mythos in superman that are similar to gladiator's were not introduced by siegel and shuster in superman's conception (you should read the article I posted) and while the similitudes are compelling just the fact that many of this similitudes appeared in superma's mythos AFTER he was created pretty much questions that theory.
What could be true is that he was the first human with superpowers, but he is not the prototype for all or most superheroes, that title goes to Superman.
Also remember that superman at his conception in 33 ( or was it 32?) was not even a hero but a villain with mental powers 😛
And I hate to break this to you, but YEP!, SUPERMAN IS HULK'S DADDY! 😈
