Batista would win this. I know all you AJ lovers don't agree which is fair but when it comes to popularity AJ Styles isn't in the s.ame league as Batista
With regards to their respective companies, AJ is more popular then Batista. TNA is often referred to as the "House that AJ built", and for good reason. Until Hulk Hogan arrived, AJ was in his prime, and was the undeniable face of the company.
But it's not a popularity contest, which is important to remember. It's who would beat the other kayfabe wise.
The guy was arguably the #1 face in 2005 and that was when the Cena era just started. He often main evented over Cena and only lost the title because of an injury, there's no telling how long Batista would have stayed on top if he didn't get injured.
That was only on Raw, and against HHH. Shortly after he beat HHH three straight times, impressively, he was moved to Smackdown and no longer main evented over Cena. His time at the top was short-lived, and it wasn't because of his injury. It was because Cena passed him. After his injury, Batista was always the guy chasing the title, rather then winning it. Whether that was John Cena getting red hot or Batista simply not being able to reach back to his level of popularity, or his inability to have consistently good matches.
I like AJ more but I've always liked Batista. He's got a good look, natural charisma and he is so hard hitting and powerful it makes his limited moveset look much more impressive.
The issue I have is whether Batista would be able to keep up with AJ. If he could ground him, he would certainly have a chance, but even against big men, he wasn't often grounded. People have mentioned Hernandez, Rob Terry, and Apollo, but he's beaten Abyss and Kevin Nash several times as well, an even bigger, harder hitting guys then Batista with limited movesets as well.
I'm not so much arguing if AJ can take Batista because he can but if I had to put one over the other I would take Batista. Not so much because of his size and power but because he has taken down some of the biggest names in WWE over the last 10 years and was a pretty good hand while they had him.
But his record against those men he beat at some time was terrible. His wins against some of the biggest names, save HHH, generally came after several losses. This is one and done, which Batista was generally unsuccessful at. AJ, as the face of TNA, was main eventing and beating the biggest and best the first time around. Batista's win-loss record against Rey Mysterio, John Cena, Edge, Chris Jericho, Booker T and Undertaker was poor, and his wins over them were often tainted or non-title.
Whatever you consider his prime, outside of 2005 when he beat HHH and JBL, he was generally a placeholder and transitional champion. His heel turn? Sure, he won the WWE title by beating down John Cena after an Elimination Chamber match, but he lost three straight to Cena after. His only other truly "high profile" win during that time was against Rey Mysterio at Survivor Series, but Rey got the win back, and then another one in a #1 contender's match.
AJ would be just too much for Batista. His limited moveset would be his downfall, as AJ is the opposite, as he has a plethora of moves he can hit you with. As to whether he could get Batista up for the Styles Clash? Ask Samoa Joe about that, who is only 10lbs lighter then him.
Batista beats those with a lot in their arsenal. Only decisive losses Batista has are against Cena and Undertaker. AJ Styles is neither Cena nor Undertaker.
But he was the face of the company until 2010, with many decisive wins over the likes of Kurt Angle, Sting, Booker T, and Kevin Nash for example. Batista has decisive losses to Edge, Rey Mysterio, Shawn Michaels(remember Backlash 2008?. He also had the steel cage loss to Chris Jercho for the World Heavyweight Championship on Raw 900 after an incredible 8 day title reign.
Batista was often outsmarted by smaller opponents, leading to his losses. It cost him against HBK at Backlash, Jericho in the Steel Cage, and Booker T while chasing him for half a year. AJ, during his 200+ day title reign, turned heel, and not only won with his incredible arsenal, but by outsmarting and cheating his opponents. What in Batista's track record says AJ wouldn't be able to do the same to him?
How much drawing power has AJ Styles had since 2005?
Quite a bit I'd say since in 2009-2010 he became TNA's longest reigning champion at 200 plus days.
I've always found AJ to be one of those "niche" draws.
"Niche" draws don't win their company's most prestigious title four times, including becoming their longest tenured champion in 2010 after 8 years with the promotion. Sure, he was surpassed by Bobby Roode in 2012, but it's a testament to his staying power nonetheless. That doesn't exactly strike me as a "niche" draw, that strikes me as a face of the company.
This isn't a knock on Batista. His first title run was a long, fairly dominant one, but he never sustainted that momemtum after returning from injury. "Placeholder champion" is the best way to describe him. Styles is the only wrestler in TNA to have won every male championship the company has. Since his first World Title win in 2003 to the end of his fourth in 2010, Styles was the man in TNA.
The only guy you could say has been a bigger long-term draw in TNA has been Kurt Angle, who Styles has had plenty of success against himself, defeating him several times for the World Title, and for Kurt's gold medal as well.
That's not a niche draw. That's being the man. This match goes to AJ.
