If you plan on autocrossing or doing track days, the adjustability will come in handy for tuning the cornering attitude of the car. For instance, I would not use my autocross settings for normal driving because emergency maneuvers would become pretty hairy. I honestly think the difference between "full soft" (a.k.a. daily driver mode) and my autocross settings (25% firm in front, 100% firm in back) is enough to warrant a completely different driving approach.
