That’s a tough one. Show pretty much got the red carpet treatment, wasn’t even in the business that long before he was feuding with Hogan and beating Flair for the title. Kane had to navigate through some pretty shytty gimmicks before hitting his stride.
Show’s feud with Brock salvaged his WWE career. Before that he was looking like a bust when they sent him to OVW. I’m gonna go with Kane , he was consistently good for a long time. Putting him together with Bryan reinvented him, and it prolonged his career. That run earned him a HOF induction.
