Having come from an Audi (2008 A4) I feel pretty qualified to give meaningful input on the subject.
Drive an A4 (sport suspension) and a 328 Sportline back to back and its easy to see the difference. S4 vs 335 isn't really a fair comparison.
While there are aspects I miss about my A4, (Quattro, firm 'click' buttons...etc) they are more than offset in the F30.
