That is easy
....... you drive a GTI DSG by putting your foot down and grasp your steering wheel...isn't life simple..
Your only problem is getting to "feel" the amount of power you give it on the edge of wheelspin...
I am truly amazed that every "manual-lover" thinks he is the Stig.....because in 99 percent of the other cases you are the losing one against a traffic light sprint... 
Besides it is really not 2010 if your soffisticated engine has to be controlled by a wannabee Schumacher fumbling with a stick in a pre-cut hole trying to get the exact moments right.... 
The comfort in daily use is.....a gift from heaven...
Do not forget you can still get your "feeling of control" by the paddle or stick...whatever makes you happy...
All those huge advantages at a moderate price......it is a no-brainer.....full stop (unless you are on a budget).... 
If getting away from the traffic lights 0.1 seconds quicker is your prime concern...go for your life. Order DSG, it's faster.
In fact, if saving 0.1 of a second is your prime concern, buy a faster car.
If however, you want to be involved...DSG doesn't cut in in the same way a manual does...if VW had even remotely trid to give the 'paddles' some feel in may have helped, but they didn't. It's just a micro-switch, much as you get on a PS3...and about as rewarding.
DSG may be faster off the line, may give better economy on paper, may be better in traffic...but it bores the tits off me, so as long as I have two arms and two legs that work, and the Government don't find a way of taxing involvement...I'll spec a manual. Hell, I'd pay the cost of DSG NOT to have it.
You don't have to be the stig to remember you are human...and to remember how to have fun in a car.
If more people were more aware of the car they were driving - by the car doing less for you - then maybe the driving standards would be higher!
...and you don't need to think about how much power to give it...XDS/TCS does that for you.
Modern cars are designed for the brain dead with little skill.
