i agree the M3 is faster on the track but most of us don't live on a race track. No doubt BMW gets more power from NA than MB but when it comes to performance models it's up to them how they get the power out so i guess MB went the cost-cutting way of just bolting on a SC to a ordinary engine.

HP isn't where the story ends,.. there's still that little matter of that insignificant thing called torque.
I understand your point on pricing, yes MB's cost more even thought the audi & BMW alternativeare just as (if not more) advanced, but at the end of the day it's always better to see a Star on the hood (or steering) rather than a propeller or 4 circles.
