My gut tells me at this stage that 18" wheels are the one to question, they may be the 'piggy in the middle', that doesn't do one thing or the other. I suspect 17" on 3-series is much the same, 16" for the softer ride, 18" for the more controlled ride. 17" = bouncy compromise.
19" gave a better ride balance than 18" on the test cars I drove. So I also am thinking Adaptive Drive on 19" may give that tigher drive in sport, but also a softer, but not bouncy ride in the normal and comfort settings. The gut says 18" is BMW's compromise, but could be neither one thing or the other.
I'd personaally love to test 'one car' specced with Adaptive Drive with two wheel sets to test back to back, the same day, same roads, etc., then I'd have a definitive answer, of changing one variable.
