How does the 7 speed DCT gearbox fitted to current model Hyundai i30/Kia Cee'd compare with VAG DSG and Ford equivalent?

Does it have similar problems with reliability and/or hesitation when attempting to pull away at a junction/roundabout?

Probably to new to know, unless someone on here has tried one. Even then, they are way to new to have any meaningful reports of how it behaves over an extended period. Personally, I'd avoid a dual clutch gearbox equipped car, certainly smaller 'dry clutch' versions which seem to be the norm on smaller cars, until such time as the problems are ironed out.
