I have an '08 SRT numbered car, auto of course. It is very disapointing the way it runs, I bought the car 500 miles away before driving one, my fault. Very smooth, quiet, handles well, but a pig performance wise. In my opinion it needs a gear change to start waking it up among other things.

It has 611 miles on it, covered up, and has not been driven in two months. So I would agree the R/T is the way I would go if I had to do it all over again, then start modifing it as to not be eaten alive by the Rustangs. Just don't have the heart to be modifying a numbered car......yet.
