Hogan and not even close.
Problem with Cena today is through no fault of his own, Vince just isn't taking the initiative to create new stars. So for years, we've had to endure Cena and a revolving door of number 2 guys.
But with Hogan, he remained on top for 4 consecutive years. When the Ultimate Warrior didn't work out, Hogan was put back in the spotlight. Before taking a hiatus in 1993, he was put back into the spotlight.
So it's a big difference, as Hogan was surrounded by talent who were held back due to WWE (or Hogan himself) having fear of losing his "spot". Cena isn't surrounded by guys who WWE feels can properly fill his role, as far as PR
goes. It's a reason we didn't get Flair/Hogan at WM, why HBK infamously overselled at Summerslam or why the final scene of WM 9 was Hogan holding the belt, even at 5 years past his actual prime or why all subsequent releases of Royal Rumble 1992 have removed all cheers for Hogan rival, Sid Justice. You don't see that with Cena. Cena, supposedly, wants the best for the business, Hogan only wanted the best for himself and his circle of butt buddies like Brian Knobs and Brutus Beefcake.
