My car is the only G30 I have driven, therefore I cannot comment on other setups but I am very happy with mine.

Xdrive, M Sport passive suspension, IAS and 20" with non-runflats (and 19" with runflats for winter)

Comfort is very subjective but I find the ride very comfortable.
Handling is beyond my expectation.
I regularly take it up to high speeds - hit the speed limiter countless times - car is very stable at high speeds.

I ordered my car without any test drives which is not wise but i did not have the opportunity.
It is best to test drive each set up if possible and decide what suits you better.
