Apart from the equipment (Xenons mainly) and the slightly more compliant ride, as well as the practicality of 5 doors, I do prefer my old Scirocco. The tramping pisses me off no end. I have to pull away from roundabouts very carefully - it's a balancing act between pulling away reasonably swiftly and tramping on the spot. I reckon my front Bridgestones will be shagged come November and I can get some Michelins.
I am looking forward to finding out how the new TT will drive as it'll also be MQB platform, and will give an idea how the next Scirocco (if they ever make another -the new golf is quite a bit lower than the last one) will drive.
The Scirocco had excellent residuals at launch, but waning residuals, lots of copycat cars and less equipment than the new GTD were my main reasons for switching.
I will probably be in a TT or S3 next time around.
