Alright, I am not going to lie and say that I don't have a biased opinion on this matter. All you gotta do is look at my sig and avi and you will see who I will be placing my vote for in this match-up. I am not going to vote based on bias though, but based on fact.
Fact One: The HBK of the last 8 years trumps anything Sting has ever done in his entire career. Think about the all-time great memorable matches that HBK has given us in the last 8 years alone. This is just a small sample right here:
Unsanctioned Match with HHH (Summerslam 2002)
First Elimination Chamber (Survivor Series 2002)
Three Stages of Hell with HHH (Armageddon 2002)
vs Chris Jericho (WrestleMania 19)
Last Man Standing Match vs HHH (Royal Rumble 2003)
Triple Threat vs HHH and Beniot (Wrestlemania 20)
Hell in a Cell Match vs HHH (Badd Blood 2003)
Team Austin vs Team Bischoff (Survivor Series 2003)
vs Kurt Angle (Wrestlemania 21)
vs Shelton Benjamin (Raw) (Who will ever forget that Super Kick at the end!?)
vs McMahon (Wrestlemania 22)
The God Match (Backlash 2006)
Hell In A Cell vs The McMahons & Big Show
The Royal Rumble Match 2007 (I will always believe that the ending to that match with HBK and Taker going at it for I believe to be 10 minutes will always be one of the three best endings to a Rumble ever)
vs John Cena (WrestleMania 23 & The Hour Long Match in London)
vs Ric Flair (WrestleMania 24)
His entire Feud with Chris Jericho in 2008
vs Undertaker (Wrestlemania 25)
Submission Match vs The Legacy (Breaking Point 2009)
vs Undertaker (Wrestlemania 26)
To the person who said that HBK doesn't push the younger talent? Are you serious? Yes, during his younger days HBK was a dick and he was pretty damn selfish, but over the last eight years HBK has had only one title reign, and that was only for a month. No, instead over the last eight years HBK has been helping build up the likes of Batista, Randy Orton, Carlito, Chris Masters, Shelton Benjamin, and Legacy. Yeah, HBK pushes the younger talent.
Fact Two: The people that HBK and Sting have faced over their respective careers are too similar in greatness to be used for this argument in any way. Sting faced guys such as Hogan, Flair, Savage, Nash, Hall, Race, Rhodes, etc... But HBK faced guys like Angle, both Harts, Piper, Bulldog, HHH, Hogan, Flair, Hall, Nash, Jericho, Taker, etc.... Both guys had a good array of people that they faced during their respective primes.
Fact Three: This is where I make my vote. I am voting based on the fact that HBK is the greatest in-ring performer the wrestling world has ever seen. HBK is great on the mic when he needs to be, but he is phenomenal in the ring every single time he steps into the ring. You want proof as to who was better in the ring? Let's look at 1995, a single year yes, but a year in which both HBK and Sting were entering/in their primes. A year in which HBK was the first person to start a Royal Rumble and win it. A year in which HBK was stealing the show at Mania and having the best match on the card, and a year in which HBK and Razor had their epic Ladder Match rematch. I think we can safely say that HBK was having typical 4-5 star matches during 1995. So what was Sting doing during this time? Well, let's go to our resident review expert on this one: klunderbunker. Let's see here:
Bash at the Beach 1995: Sting vs Meng Grade: D
Fall Brawl 1995: Hulkamaniacs vs Dungeon of Doom Grade: D
Great American Bash 1995: Sting vs Meng Grade: D+
Slamboree 1995: Sting vs Big Bubba Rogers Grade: D
Halloween Havoc 1995: Arn Anderson/Brian Pillman vs Sting/Ric Flair Grade: B
That is just a small sample of his work on PPV that year, but as you can see, besides one B, it wasn't that good. Now people can complain and say "BUT LOOK AT HIS OPPONENTS! HE HAD SHIT TO WORK WITH!" Very True, but you know what the mark of a great, great, wrestler is? When they can take shit and turn it into gold. HBK was able to draw great matches out of Kevin Nash, and Psycho Sid. What could Sting do? Nothing. He was complacent with his shit, and just rode with it. HBK would have never settled for that. HBK never settles for shit, and that is what makes him a legend.
HBK>Sting. That is all she wrote.
