People heavily overrate the MP40. Was it an awesome gun? Yes. It wasn't like it was the only viable gun in that game though. I personally perform better with quite a few other guns.
People act like it was the only usable weapon in that game which is very wrong.
It doesn't matter how well YOU could do with it. What matters is that it was a 2 shot kill with Stopping Power, ONE to the head. Also had a decently high fire rate and clip size, which made for easy spraying. Not to mention the hipfire. It's basically a laser beam.
