On paper this looks like a really hard decision, but the more I thought about it the easier a vote for Guerrero it was.
I mean, if we look at their entire careers it seems fairly close; this tournament is based on primes however, and Guerreros stretch from 2004-2005 was more significant than Owen's 1994 for me.
It really, really annoys me when people say Eddie was overrated due to his death. I strongly disagree. I mean, he won the World title and retained in a Wrestlemania main event over Lesnar and Angle. Neither were clean, but while he couldn't hope for the help of Goldberg in this tournament the manner he defeated Angle was fairly typical for him.
Furthermore, towards the end of 2005 he was back in the main event and seemed certain for a second world title reign. That's more than Benoit ever got. For me, Eddie was a bigger main event player than Benoit at the time of his death, which was also Benoit's prime. If Eddie had survived, I'd be shocked if he didn't go on to have multiple title reigns and be considered in the same league as the Jerichos of the wrestling world.
Owen Hart is different. I DO feel his death pushed him to a bloated level of percepted overness. He was great in the ring but never reached the top echelon - while I don't want to be hypocritical and claim that Eddie would be a multiple champ without acknowledging that Owen might of took the title at some point, there is simply TONS more evidence to support a second Guerrero reign compared to Owen reaching the main event when he was lowermidcard at the time of his death.
To be fair, I considered everything and Owen has something going for him. During Eddie's prime he had a hot feud with another top cruiserweight, Rey Mysterio. A feud that Mysterio dominated the win/loss of. Eddie hasn't had problems with cruiserweights in his career, but if a guy of similar stature and style to Hart can crush him in his prime, maybe you can make a case for Owen. That said, Guerrero dominated most of the fued and the Mysterio wins came across as underdog upsets every time. Owen IS a different worker from Mysterio too, and his focus on submission/technical wrestling will play more into Eddie's hands than Mysterio's gutsy, resistant and unexpected offence.
For me, no factor points towards an Owen win. His biggest win, going over Bret at Mania, can be put down to distraction by Bret as he focused on his WWE title shot later that night, and it's one of the few peaks of a fairly mediocre career.
Guerrero to the second round, and its not even close
