Err,
It's faster (despite VW's claims)
It's one of the best manual changes in any hot hatch and a delight to use,
It's always up to the the driver what gear you are in, not the intuition of a computer,
The manual never misses a gear - sometimes DSG doesn't respond at all, sometimes it chooses the wrong gear,
You always, always know which gear you are in,
It doesn't break,
It's cheaper (much),
It doesn't pause then lurch on initial take off,
Launch control is always engaged
You have a choice to heel and toe (and the pedals are absolutely perfect for this)
It's tactile, far more engaging and a wonderfully integral part of the car/driver interface,
It's a real gearbox and not two tiny, tappy switches hidden somewhere between the steering wheel and control stalks,
If you've got fingers bigger than a childs you don't have to engage main beam and the rear wiper to fit the gear lever,
Was that two taps? or three? Oh noooooooooooo!
