Makes sense, because IMO Roode's character is one you will appreciate more over time and the more you see of him the more you will love him; whereas Bully when you first get to know him with this gimmick will blow you away from the start, but he doesn't have as many different subtle nuances in his gimmick like Roode does.
Henry from 2011 would be up there, but not since he dropped the title and was injured. the only other WWE heel that is a really good choice IMO would be Barrett, but he's been gone for too much of 2012 to be on my best heels of 2012 list. Other heels in WWE are awesome, but don't really fit the mold for what I think of when I think of a great heel. DZ & D-Bry for example are closer to being tweeners than true heels, both in action and crowd reaction
