Folks mention lost of hitting power from 200 to 400. That's true of MGs, but the MG/FFm on the Bf109 are explosive cannon shells. They derive most of their destructive power from high explosives inside the shell. There's much less punching through things.
These guns are better at longer ranges, assuming you land any hits. They are more powerful if they land, but are many times harder to land at longer ranges.
Just an FYI, in case folks were overlooking that.
