[Marvel] why does it seem like Captain America is so much stronger and versatile when he faced The Winter Soldier/Hydra agents, but barely able against Loki and the Chitari?

I actually just watched Avengers again yesterday and the others in the past week. 

* First Avenger: Cap literally never slows down. 

* Avengers: Loki toys with and manhandles Cap in Germany and fake surrenders when Iron Man blasts him. Only Thor and Hulk can physically deal with Loki. He's a thousand year old space god. 

* Avengers: Cap actually fucks up a LOT of Chitauri and easily early on. It's not until he's thrown out a window by the alien grenade, falls four floors into a car and gets shot in the stomach by an alien that he starts to fail. 

* Winter Soldier: He doesn't even slow down until Bucky repeatedly shoots him. 

Rule of thumb in writing a Cap feat of action:

* Could *some* human *theoretically* do this physical action? If yes, so can he. Repeatedly.
