Who would you say are hulks most trusted friends among other heroes disregarding fellow Hulks of course?
Jim Wilson comes to mind. Silver Surfer and Namor are Hulks friends as well. Mike Berengetti his boss from his Fixit day's was mentioned as a friend by the Hulk's professor persona likewise. I know their are others but that's all that comes to mind right now.
I would say that Rick Jones is definitely Hulk's best friend - though technically he is a Hulk at the moment he hasn't been for the majority of his existence. In addition to the characters already mentioned, most of the Warbound would count among Hulk's best friends.
Sentry and Hulk were best friends.
Tony Stark has recently become more of a rival buddy of Bruce Banner.
Spider-Woman and Hulk seemed to have gotten pretty close in Avengers Assemble.
Reed Richards and Bruce Banner knew each other before they were heroes and were friends, but I'm not so sure how they feel about each other now after World War Hulk.
Strange and Namor used to be close to Hulk, but again not sure where he stands after World War Hulk with them.
Silver Surfer is nice to everyone so I don't see why they would stop being friends.
What do you feel about Hulk's relationship with his most prolific sparring partners; Logan,Thor and Thing?
I see the Thing as the longest standing and best heroic rival to the Hulk. They are not friends.
I see Logan as an annoying, pesky acquaintance of the Hulk. Not a friend, either.
I see Thor as a great rival who became a friend to the Hulk after the first Red Hulk story arc.
Rick Jones. Though right now rick has been depowered by hulk and went to red she hulk to warn her hulk was coming. So I'm not sure how the friendship will go.
Also the Sentry made Hulk feel good with his "golden light" at some point though after world war hulk I we haven't seen much.
With the Doc Green run i'm not sure hulk will have much more friends.
