I went with Orton here because I truly feel that Orton is better than Funk. I know that some old school guys might really flip out at the mere mention of this but just consider the facts. Funk won the NWA title once and held it for fourteen months. That is good but not earth shattering in an era where long title reigns were common. Orton has won the World title 9 times in WWE. I know titles change hands too often in this era but even then, it is an impreessive achievement. Not too many modern day greats have been able to have so many title runs.
Funk may have been the face of NWA during his 14 month title reign but Orton has been the face of Smackdown in 2011 and the top heel in the company for most part of 2007-2010. In 2010, when he was on Raw, he equalled John Cena's reaction on many an occasion and if you go by crowd pops, Orton may be the biggest face in the WWE even at this point. Terry, for most part of his career after his World title run was used as the guy to put other guys over.
Funk has been in some very brutal matches but so has Orton. Unlike Funk though, Orton has won most of them except for the ones against Cena and Undertaker. Funk was the guy who even lost to Foley, who has lost to everyone, including Orton. Funk may have been a great technical wrestler in his prime but Orton has beaten his fair share of good technical wrestlers like Benoit, Jericho, Angle and Punk.
It seems to me that whatever Funk has done in his career, Orton has done better. Even if you strip them down of their accolades and just look at the type of wrestlers they are, I think even that favours Orton. Orton is a bit lean but a tall, good looking guy muscular guy and because of that I feel he would have been a star even in the 1970's whereas Funk, had he debuted in this era seems to me like someone who would be a more talented Chris Jericho. Great wrestler, great promo cutter but the sort of guy who lacks just that something that would make you the face of the company. He just seems like the perrenial upper midcard sort of guy to me.
Vote: Randy Orton.
