As mentioned I was expecting sport mode on my F10 with adaptive drive to be very tight, as BMW mentioned that it was supposed to make the chassis tighter than M sport suspension. The sport mode is only about right, and the other 2 modes, normal and comfort are redundant for me. There is not any M sport suspension F10 for me to test but I really doubt M sport suspension is less tight than adaptive drive in sport mode. A forummer LARS mentioned the M sport suspension feels the same as dynamic damping in sport mode

My view is that the M sport suspension may be a better choice, much more economical, not needing to keep on pressing for sport whenever the car is started, and with less parts to go faulty. The main disadvantage is that it does not have the active anti-roll bars (which are highly effective and good) that come with adaptive drive but after market fixed bars may be an option. My tyres are Contisport 18 inch runflats, and my guess is that the ride would still be fine with 19 inch.
ps I'm not sure whether the standard setup is tighter than normal mode with adaptive drive.
