I've recently driven a new 997 with PDK and a new  M3 with DCT.

As gar as the transmission goes, I liked the BMW much more. The shifts were astonishingly fast and smooth - the car is just not unsettled in any way, even during downshifts into 1st gear. PDK was good, but just didn't seem that good to me.

The BMW was an M3 cab, so I don't think its fair to compare performance, but I can say that I thought the steering of the 911 was MUCH more communicative  and precise. The M3 also felt very top heavy to me, but I am used to the lower ctr of gravity in a 911. It must be remembered that the M3 is a sedan. The center of gravity makes a big difference.
