When I was looking to buy a GTI, I looked at DSG. Then read abou problems in America with the DSG which put me off so bought a manual instead. The problem turned out to be the mechatronics unit.
I sat in a mate's ED30 DSG - he floored it, and as it accelerated, no lurch, no changing up/down revs, just a smooth strong pull all the way.
If I'd the opportunity, I'd go DSG all the way.
