They're all a little apples/oranges. I agree that the RS5 is probably a better comparo to the E92 M3 (In fact, European Car did just that last month, and it was a great read for a fan of either marque) but I can only compare what I've driven.
By no means does the 335 compare to the S5 though. Even a fully loaded MSport package 335 with every possible option falls well short of the S5 in nearly every category, sad to say. Performance-wise I imagine they are similar (probably pretty close really in terms of acceleration now that I think back on it) but if it were the same money I'd take the S5 every time.
And the new S4 can't be compared to the E90 335. Much nicer. Even though it gives up something in performance to the E90 M3, you still have to put them side by side. (and a chipped 3.0T S4 is a beast, FWIW.)
