Yep, I have a 718 GT4 in manual and my friend has a 718 GT4 with PDK. His is completely standard and has had a geo setup but no parts added. My car is modified with a LWFW, sports exhaust silencer and some Motorsport parts to allow a more aggressive geo. I've driven my on track and I was a passenger on track in the PDK car, both running Michelin Cup2 tyres. So not quite a like for like comparison, but pretty close.
I'm probably going to be stating the obvious here, but here goes anyway... For ease of use and consistent lap times the PDK box is clearly the way to go. The shifts are impeccable both up and down and it allows you to keep both hands on the wheel at all times. Every shift is identical to the last and perfect. The car is more settled with less weight transfer, smoother all round and very slick - effortless. Gearing isn't that much shorter than a manual and not enough to make a substantial difference in my view. I found that my manual car had more character with some more mechanical noise and interaction. PDK seemed too easy for my tastes, less raw feeling and less of a challenge to really nail a good series of bends, shifts and braking points. My car is much harder work to get right consistently but when you do it feels really, really good. I also think on the road it's a much more enjoyable option as it feels so rugged, mechanical and old-skool. Adding auto-blip on track really helps on the downshifts of course, but you still get that mechanical connection to the car via the use of the clutch and a manual shift. My take home view was that if you track a lot and you're chasing the absolute best times, or want an easier life on both road or track, then PDK is the way to go. Me, I'm completely satisfied with my manual 'box as I find it fabulous to use both on and off track and I enjoy the inconsistency of a manual gear change. The cars felt quite different to me and I think people will definitely prefer one over the other depending on what they want from a car.
YMMV, other opinions are available etc etc. Both are superb options, there's no right or wrong choice!
