Most wrestlers I've heard interviews with usually talk about how great of a guy he is.
Let me direct you to a bret hart or shawn michaels interview
Both guys freely admit to being dicks themselves, though.
It's not like everyone loves Hogan, but many do, particularly if they were never in the position of angling to be put over him or something else that would lead to butting heads. Outside of "creative control" headaches, he is generally spoken well of and said to be friendly.
I would like to add that after Hogan took part in the Hasslehoff roast and made fun of his recent lack of a career, I had images of TNA bringing Hasslehoff in to feud with Hogan, including attacking him backstage and KO'ing him with a toilet seat (this was when Hogan was suing his wife over a toilet seat) with the words "Hire this!" written on it.
Daniel Tosh should be part of this if it ever happened. He's a legit wrestling fan, does a good Savage impression, and is another Comedy Central regular. That said, a Hogan roast will probably never happen unless it's a WWE produced thing while Hogan is on good terms with the company. Hogan laughed for the cameras at Hasslehoff's roast, but you can kind of tell he didn't want to be there getting ripped on.
