Here the info I have regarding this suspension topic for MY13.
M Sport Package $2900 includes Sport Suspension according to the window sticker on MY13 vehicles. Unless this is a typo by BMWUSA which I'm not surprised considering what happened last month on their website regarding the 445hp typo.
Dynamic Damper Control is a $1000 add-on which was part of the M Sport Package in 2012.
Dynamic Handling Package is a $3500 add-on with DDC & ARS/Adaptive Drive, this was part of the M Sport Package in 2011.
As to which configuration is better, it's strictly a personal choice based on one's individual driving style. I prefer DDC MYSELF, since you can at least adjust the settings from comfort to sport + so you have a slight range to play with. With the sport suspension or Adaptive drive, there is no driver setting, it is always on. Just my $0.02.
