We've had a DSG Mk5 gti since 2007 and it's one of those things that I'd find very hard to give up now. We hired a car for a week a few months ago which was a manual golf (not a gti) and it was a right pain. (Though to be honest, the first few times I did come to a junction and wonder why it had gone all quiet before remembering what the other pedal was for

)
Even if you like the sound of DSG, it is an extra bit of machinery in the car, and it has a 40K oil change requirement which was a bit pricey. We'll need another soon!
Our car is strictly a "Fuss Free A to B" machine, so DSG works well for us, and I suspect this is the thing which determines what people prefer.
