@acer51: Someone made a point on a daredevil thread earlier that the thugs in the Daredevil show are just tougher than other thugs. They were still fighting after getting thrown through a door and having a microwave hit them in the face. They might just be tougher than those guys, who went down easy
Natasha however fights at this skill level consistently, be it equally dangerous mobsters or alien invaders.
You may take my word for it these feats are consistent or if you wish I can provide proof.
That being said Natasha is considerably more skilled than Daredevil and there is no logical way around this.
