The Sportsteering in comfort mode feels a bit remote and really electric(which it is off course) not really BMWish, but I already got used to that for the last 1.5 years in my ex F10 5 series.
On the other hand, the sport mode is the BMW way to go and doesn't differ very much from the hydraulic steering my former BMW's had. Actually it's very very good. It's beefy, direct and gives you a connected feel to the front wheels, very unelectric imo, very BMWish.
I have the Adaptive suspension, 19"and the Bridgestones fwiw.
