The 330d and 328i are very closely matched in performance. Although the 328i is more nimble and therefore quicker in the twists. 50 - 90 mph, typical motorway joining speeds both are in the 7 second bracket.
You certainly have to work a bit harder for the performance in the 328i. I have an colleague with the F30 330d and rolling on from 60 to whatever speed you like there was little in it. The big difference was all he had to do to access the performance was stamp on the throttle, whilst I needed to be in the right gear. If youre lazy in the 328i then you will get left by the 330d.
