Nothing to do with the comics or who I want to be the best, we don't know own the full details of the fall, Hulk might have been calmed down enough when he landed that when he did get hurt he was dazed for a while and this is when he reverts to Banner who loses consciousness.
Or Hulk had calmed down enough by the time he hit the ground it did indeed knock him out. Either way, using it to say Thor is tougher is nonsensical. You could easily argue it the other way and say Hulk hit several floors of solid concrete when he landed where as Thor landed in a field.
For me Thor is more powerful and durable than a baseline Hulk. So if that Hulk hit the ground it could have knocked him out.
At the same time, we could easily say Hulk took jet machine gun fire and laser blasts full on in TA, while Thor was seen as dodging/diving out the way of both. Same with the Quinjet fire in AOU. You could say Ultron took down Thor in AOU (I personally think Thor was playing along with Visions plan, but I have seen others argue Ultron beat the crap out of Thor) yet in both encounters Hulk had with Ultron in the finale Hulk made quick work of him.
See where I am going here? We could argue these little details all day.
