If was stated on panel that WWH is much more durable than all other Hulks (in his fight against Logan).
But we go on a character's history and past feats to gauge durability. For example, I can show you scans where Thing has hit a weaker Hulk (savage) in the face with all his might and didn't put a scratch on him. All he did was knock him back.
Thing and Hulk fought numerous time and Thing never did that type of blow on Hulk ever. To do it on a more durable Hulk is kind of pissy I would say.
