1) Looks: 335i + M-sport ~ 335is

3) Tuning (OEM): 335i + PPK ~ 335is
4) Tuning (aftermarket): 335is > 335i
In my opinion (for non DCT) the better choice is 335i + PE exhaust + PPK + nice/quality wheels (the price for a new car will be the same as 335is).
The exhaust wont be the same.
N55 and n54 have their own distinct exhaust note.
