Thanks for all the comments.
In terms of performance the 328i is a little quicker than the E90 330d and the F30 330d a little quicker than the 328i. Small differences though in absolute performance but big differences in the way the performance is given.
Choice of wheel is purely a personal one based on looks, I wasn't keen on the design of the 19s.
I went for the passive rather than active M sport suspension. I tried the active and (for me ) it was waste of time. I prefer my cars firmly suspended. The passive suspension is superbly judged and a revelation over the E90.
Big difference over the 330d is just how quiet and smooth the engine is. First tank of fuel looks like coming out circa 36mpg.
I promise anyone who has an F30 MSport on order you will not be disapointed.
