I simply have to chime in here. After 6 years of driving, autocrossing, and racing a 986S with a 6 speed manual, my daily driver is now a PDK C4S.
So I am probably one of the few (or maybe the only) posters who have actually extensive seat time in a PDK car. And I can tell you: PDK is the best of both worlds. Normally I leave the PDK in manual mode and shift using the paddler shifters. However, when I am stuck in stop and go traffic I simply switch to automatic mode and don't have to worry about the clutch. And in manual mode it's just as engaging as if you have a stick and a clutch. It's the best of both worlds - seriously.
Track season starts end of March and I will do one session in manual only, one session in in Sport Plus mode in fully automatic and one session in Sports mode, with me doing the shifting when necessary. I am pretty sure that if there's any difference it will be to the PDK's advantage. The argument that you are no longer in control with a PDK makes as much sense as not being in control without torsion bars or carburetors or drum brakes.
Guys and Gals, drive a PDK car, move the shift lever to the left (in manual) and then shift (hopefully with paddles, as the standard Porsche "Rubik's cube logic" buttons suck big time) and then please don't tell me that you felt you were not in control all the time....
