^^ Nice examples Hit and Run, but remember that after She-Hulk got pounded by Titania Spidey beat her.
There's a few things to this fight.
1. A thunderclap REALLY screws Spidey up.
2. She-Hulk has some durability issues that regular Hulk doesn't usually have. It's well within reason for Spidey to win this fight.
3. That thunderclap Hit and Run showed was when She-Hulk was very very pissed off. If she gets to this state and does that, Spidey's screwed. If she stays in regular mode and is calmer, Spidey not only has a legitimate shot to win, but he's probably the favorite.
So there you have it....like any good fight it could go either way. Draw She-Hulk to potential and she thunderclaps her way to victory every time...but she wouldn't always be angry enough to pull it off.
