Def agree that my experience of manual has been great so far. I never even considered an auto until I sat in my friends new GTi with DSG. It seemed like a great compromise of the ease of use in traffic, but it was the first 'box that seemed great when upshifting on its own, but also on manual over-rides, which seemed to respond pretty quick. If I was ever seriously considering, I guess I would have to try them both out.
But for now, my vote is with manual.
