"Is a manual contributing further to the driving experience when really going for it?"
Ahhh.....Definitely! But aren't we straying off topic?
No, most definitely a manual stick is not contributing at all.
It is all (and only) in the mind of the beholder.
Following short reasons :
Take a look at F1 sport, all on auto stick which is not mandatory but the best solution.
The old system as we known from after WW2, yes truly we can see not sporty.
DSG will shift gears (up or down) in an eyeblink, and doing this without losing traction
or going down in rev's. Meaning one can safely shift gear also in cornering.
This was developed/patented by Porsche (with Borg-Warner), as PDK, we can all agree to them
as producing sports cars.
Also faster times in accelerations, to any speed for that matter.
Apart from this, the DSG makes a better car; as a total.
With the DSG it is much more a multi purpose vehicle, comfy when needed (traffic jams or city
use) as well as sporty when possible.
Also interaction/communication with an ACC and the new traff/jam assist is better.
LASTLY, and on topic, my last car was the Golf-6 GTI a with manual stick.
In 4 years one repair, yes indeed a new clutch.....(Can hear the comment flowing in: My driving
to be blamed, but according VW an error in producing this.
Love to drive with the DSG, only disadvantage I can cough-up is the higher price for purch/maintc. So if this is in Your budget, go for it !
But bear in mind that IF a good Stage1 (or higher) tuning is in the pipeline, the DSG will need to be worked on also.
