I think if you look at NXT, the one guy who seems like he would belong in a WrestleMania main event is Nakamura because of the aura and the buzz that he gets. He is able to grab the attention of people who don't really know who he is right away with his mannerisms and entrance - by the time he gets to the ring, you are kind of hooked.
I'm a lot happier on RAW. I actually can't overthink how much better I think I am on RAW than I was on Smackdown. And I don't really know the reason why that is. I feel like I look more at home here, and I feel like I look like I belong here. It's pretty obvious that RAW's the place for me.
