There is NO delay when you control the clutch with your foot-I am not sure what you mean by "Just like a manual". The delay/anticipation thing that DSG does when you press the accelerator is exactly why I traded my 2010 JSW DSG. It is not bad once you are rolling, but the transition from foot on brake to foot on throttle is followed by a variable pause in DSG. Stark contrast with a 6MT...when I control the clutch, I lift my left foot, and the car instantly goes.
I disagree with their comment about downshifting though. Maybe they didn't know about tiptronic control(?). It is there if you need it!
Look at post 261 in this thread, and all of the ruckus that followed!

Yes, you can learn to anticipate when DSG starts to go, but I found it to be variable, which made tight merges from a stop a little unnerving. I had to go back to the kind of clutch that I control. In tight traffic situations, brief delays in acceleration from a stop can cause near misses and scary situations merging into aggressive traffic.
But for less aggressive traffic situations, I really enjoyed the DSG.
