I'm voting for Edge. Why, you ask? I'll tell you why: Fuck the Undertaker. That's why. Satisfied? Eh, I don't care.
Seriously though, it's as simple as this. I've known of The Undertaker since he first debuted in the WWF. That was in 1991, and during that entire time, I would say there are roughly ten matches out of his entire career where I was actually entertained while that man was on my TV. All his promos and angles were shit, and so were most of his matches. I've never found the guy intriguing, at all. Do I respect him? Yes, but at the same time
I downright hated him all throughout my childhood, and it wasn't until his match against Kurt Angle on Smackdown in New Orleans where I finally started liking the guy. But then the next week he was shit again. And he remained being shit, unless he was in the ring with a fantastic worker, where, when 'Taker was, to his credit, he was able to get some classic matches under his belt. However, that's not enough for me to vote for him over someone like Edge.
I've liked Edge from the start. The Brood was awesome, and Edge stuck out to me more than any other member in the faction. He reminded me a lot of Raven, for some reason. But yeah... right from the start I dug him. And it wasn't too long after that he started participating in some of the greatest tag team matches to ever take place. And not only were the matches absolutely tremendous, but so were the promos. I mean, this guy cracked me the fuck up at will. He was truly hilarious. Once the tag team deal was over, he had a great singles run before his injuries, having great matches against Kurt Angle, Chris Benoit, Brock Lesnar, ect. Then the neck injury happens and he's out for a long while. He returns and WWE sticks him with this serious babyface character, and it just doesn't work. So they turn him heel, and Edge goes on to have a good feud with Shawn Michaels and wins what was in my opinion, the best Money in the Bank match to take place thus far. So Edge does that, bangs Lita, gets shit for it but looks awesome in my eyes, beats the living hell out of Fat Hardy when that douchebag returns, has one of the greatest cage matches in history against said douche, and then goes on to win the WWE Title and be the first heel to actually draw boos against John Cena since Cena's transition to Raw. And after that... week after week Edge has been consistently one of, if not THE, most entertaining wrestlers WWE has to offer.
That's why Edge is getting my vote. He's been in the WWE for 10 years and entertained me the entire fucking time, where 'Taker has been there for almost 20 years and has only given me a great match here and there. I don't give a shit about kayfabe or 'Taker's legacy; I'm voting for Edge simply for that reason and that reason only. And to me, its justified.
