i had the sport suspension and the pss10. Not sure if sport = msport but oem sport suspension is crap, it sits a tiny bit lower than stock but handles horribly. Bumpy on straights, excessive swaying on corners. PSS10's on the other hand is a whole different ball game. It handles much better and without much of a compromise for ride comfort. You need a good garage to install your coils for the PSS10's though, some owners report squeaking from bad installs. Also the PSS10's sit pretty low at the highest level, so if you live in a parking lot with huge speed bumps, your going to be in a world of pain.
I don't believe comparing the Msport suspension to the PSS10's would be fair, i think a better comparison would be msport suspension and Koni Street Coilovers.
