pretty good summary. Straight line and track performance however I think you'll find the RS5 won't be far behind the M3 if it's a non-expert driver at the helm. The M3 can put a big gap on the RS4/RS5, however if you put both cars in the hands of most drivers, the difference will be negligible. This will be most apparent at the dragstrip or while racing a friend from a dig somewhere...the RS5 will always give you 98% of its capability, while the M3 will require quite a bit more input.
That's part of the allure of the M3 of course...it's a bit more raw and it's part of the knock against the RS5...it's a hair disconnected feeling being a little more computer aided and heavier.
