I think the actual comparison is DCC vs. non-DCC. I went from stock (Golf) suspension, to B8's/H&R's, to DCC on the same car, same roads, same wheels/tires/pressure... all within about 4,000 miles. The difference is between DCC and non-DCC (stock or otherwise) was very obvious to me.
Until I had the basic settings done for the DCC module I drove for a couple weeks with the suspension error in the dash. In this failsafe mode the module doesn't provide power to the dampers so they are inactive, operating like standard dampers. Big difference here too, and that change from inactive > to inactive was compared in the span of 2 hours.
