I, too, went from a FN2 Type R. I loved that car but now have a MK7 R. The only reason I chose the R over the GTI was purely because I got a great deal on a new one earlier this year. I did try a DSG and whilst it's a fantastic gearbox it just didn't feel as engaging as a Manual.
You won't regret getting the GTI though. I always thought my Type R was quick and nimble but was amazed - and still am - with the Golf.
Have fun with the search.
