I can honestly say he wouldn't get my vote either. Maybe I'm the worst wrestling fan ever because I watch wrestling to be entertained, and Benoit was boring. Some say he's the best technical wrestler ever to enter the ring, I say okay, but he has no charisma, promo skills weren't there, and that's my biggest complaint with Reigns who I love, and he'll be a three time world champion next week.
So yea I find Dean Ambrose wacky, funny, does things that only he can get away with, and makes me want to watch him to see what he'll do next. As Jon Moxley his in ring work was much better than it is now, that I'll blame on the WWE.
Benoit went as far as he was going to go, with Ambrose the sky is the limit it they let him. But then I'm the kind of person who goes to the track and bets on a horse because of it's name so make that of it what you will.
I agree that Benoit went as far as he was going to go. That's further than where Ambrose has gotten. If this match comes up again a year or two from now I might pick Ambrose. As of now though he hasn't accomplished anything that warrants a vote over Benoit. But I get it that you weren't entertained by him. That's fine. I think you are very much in the minority there but I can't say you're wrong for not being entertained.
