3dr DSG is the win for me but that is because my car is a totally hobbie car so whenever I need to be grown up and visiting family we go in the wifes 4x4 :). So I can see the 5dr is more practical when ferrying family around unless you remove the back seats from the 3dr, open the boot and just chuck the family in haha
I love DSG and would never go back to manual mainly because I am probably lazy but just makes it feel more sporty to me even though you are doing less sporty driving skill than a manual.
Suppose the real question is if practicality was not needed would some pick 5dr peeps move to a 3dr?
