In terms of who will hold the big one first, if both eventually do, it should be a unanimous chorus of drew mcintyre chants. But that doesnt rule out peoples preference. Drew is found to be quite stale and boring by a fair chunk of the IWC and cody in comparison is praised as being the better legacy member but just being stuck in a rut currently.
I'm sure if we had a poll of preference it would be something like a 3:1 ratio of cody votes. But I myself can understand that and yet prefer drew as a superstar. Drew's character in itself is one thing that aids him to be more likely in reaching the top. The last guy to really make cody's gimmick successful was HBK and he was only really in the pretty boy gimmick in about 93-94, thats yonks ago.
I stand up for drew not because of his talking, he does has a slightly afeminite voice and is quite underpowering in his delivery and monotinous in tone. I elect drew because of his in-ring gimmick. In the ring he has a very individual unique persona which is a very easily frustratable and overly violent man. All the little things like when he stomped on matt hardy's head, when he kicked r-truth on his second week, when he pulled john morrison under the ring to get a win for a shot of the intercontinental title. All of these little in-ring events are what makes drew special and different. It's what makes his character feel real. In a real fight you don't just leave a guy after hitting him a few times to gloat, you stomp on his head so he can't get back up to win, its just a type of attitude escapism in a PG world.
That in a nutshell is why I like drew, that and he has an awesome theme and entrance...and his facial expressions are really maniacal also. I like cody also more than the average guy, but I realy don't like his gimmick, and if that changes then I may re-consider my answer. Until then, hands down, chosen one.
