My 06 911 C2S was a manual and I really enjoyed the level of 'engagement' that gave me with the car.
I've driven a number of PDK 911s in recent years and my next one (if there is a next one) will be a PDK - I'm very impressed with it.
Are people losing the love for a manual? I've owned one of these dual-clutch gearboxes, albeit on a VW, but I still prefer a manual. I even prefer the crap notchy manual I have on my current car. I suppose manual cars, even they even keep making them, will be cost options soon.
I've just committed myself to a manual 981 Boxster over the PDK option. Porsche kindly gave me a Boxster S with PDK to play with over a couple of days and, frankly, it was awesome. Compared to dual clutch gearboxes I've tried and owned previously it was seamless and lightning fast. However, the big issue for me is that I can't get on with using the paddles. Maybe it's a question of practice or simply that I'm too old and set in my ways to adapt but I just don't find them intuitive. Particularly when I'm pulling away from junctions I always seem to be searching for the paddle. I can imagine that if I were having a spirited drive on a road that I know well in a car that I know well they could be a lot of fun but for the rest of the time I imagine I'd just stick the thing in Drive. Whilst I'm happy to leave all my gearchanging to my Land Rover, that's not what I buy a sports car for.
I had a manual 911 996 a number of years ago and said I would never buy a Porsche with anything else. Recently bought a 911 991 with the PDK because it is simply immense! The manual just didnt come anywhere near. Sticking it into Sports Plus mode with Sports Exhaust on and messing about with the gearbox is one of my favourite things to do!!
As someone else said, maybe it's an age thing. PDK is faster and more efficient, but every time I've had one, I just end up sticking it in drive. Currently have a 1989 911 with manual which I decided to keep over the GTS with PDK I also had at the same time. If it's a car you'll be using regularly (rather than fun) the PDK probably makes sense.
