Here we go again. You make one good thread, and follow up with something that sounds like a cry for help as opposed to an actual thread conveying a point.
Your question makes no sense. Who was more 'fit'? As in who was better prepared to take Hogan's spot? Nobody. No one was taking Hogan's spot during Hulkamania. Warrior was given a chance at being competitive with Hogan when he beat him at Wrestlemania, but once the higher ups seen how nutty he was in real life, the WWE cut bait on him within that next year.
Savage was never fit to lead a promotion. He's a great role player, but leading a promotion wasn't his deal. He could draw and have some excellent matches in his day, but to be the center of that promotion, you had to be marketable and able to deal with people, something Macho Man's character wasn't made to do. The Macho Man was unstable, mean, and not a people person. So he wasn't fit to take Hogan's spot.
So your answer is none of them. The reason Hogan had his spot was because he was the biggest draw in wrestling. Warrior and Savage couldn't pick up that slack. All they could do is maintain their performance as great hands in the ring. Well that was in Savage's case. Warrior proved to be a liability after a while and then he was gone.
