i can tell you from the experience i have from my cars. the GS's CC is the "35% quicker" version, which does feel more crisp and precise compare to the 05 QP's DS. the DS is slightly more relaxed especially at low rpms. at high rpms there is not much difference.
the CC in the 90th spyder (which is essential the GS's) likes to blip more on downshift than the DS.
