I'm opting for the DKG mainly for 4 reasons:
1) Convenience of an automatic mode for daily driving especially traffic: I live and work in a big busy city (Chicago)
2) Safer and faster (theoretically) on the track: I'm not the most adept when it comes to heel-toe shifting and in fact have spun many rwd cars from blown shift entering a turn.
3) My GF promised she will attend track events with me again because she refuses to drive my RS4 or any manual car for fear of blowing up the tranny or engine. She is even less adept at heel-toe-shifting and has no motivation to learn.
4) Launch control! Although I'm sure our version will be dumbed down
