Cena. At least Cena would be able to carry Hogan to a hopefully decent match, Austin wouldnt be able to do the same thing.
I have no interest in seeing HHH and sting already had his match with Hogan at BFG.
Having seen Hogan in the ring 3 months ago at TNA in manchester i can honestly say i don't want to see him wrestle again. While he's in the ring you become that 5 year old Hulkamaniac again and you cheer every punch like it was still 1991. But to see him attempt to walk and move around the ring is sad Hulk has done enough for the wrestling business i just want to see him go home and not destroy his back any more.
If there was a way to get the Hulk from the 90's back vs the austin from the 90's then that would be the pick.
Already seen Hulk vs HHH already seen Hulk vs Sting. Hulk vs Cena would be a 2nd choice.
Hulk Hogan can barely move these days. He's too out of shape. Hulk Hogan vs John Cena should have happened in 2005 or 2006 if it was going to happen at all. The match wouldn't have been a 5 star classic or anything but it would have been memorable.
If his last match had happened in a WWE ring, it'd HAVE to have been putting over John Cena sometime between 2005 and 2007. Cena has been the face of the company for a while now and Hogan would've helped cement that status for him.
