You say that Hulk takes Spidey for sure, yet Hulk had one of his punches stopped by Thor with one hand, and Thor took severe shots from Hulk with no lasting effect. This should clearly emphasise that Thor >>>> Spidey.
Both Thor and Hulk, and additionally Iron Man, can beat Spidey.
They're all definitely stronger (even Iron Man could kick cars away, nonchalantly, with one leg) and they're all definitely more durable. Bearing in mind that Hulk was completely unharmed the whole movie, Thor took punches from Hulk with no effects, and Iron Man took Thor's hammer and Cap's shield thrown at him without severe damage.
