I can't give you times for how quick the DSG does 2 or 3 gear drops (yes it can do 3 gear drops) but I know it's f--king fast and I doubt even an automatic is doing it any quicker. As for why develop both systems, well that's simple because while DSG is very good at performing like an auto it isn't AS
good as the real thing and because of this I believe at the minute we won't see it fulfilling the role any further than in sporty car applications. So no luxury cars like the Bentley or Rolls Royce just yet.
