I think it depends on what you want. I am getting a 2.0 TDI sport because I want the mid range grunt and the improved fuel efficiency. The TFSI will give you a far better 0-60 as long as you work it hard. The TFSI is as sporty as it gets at the moment, my concern is that there will be a lot of disappointed people out there when the more powerful engines arrive.
I just wish the wait time was less, mine is on a boat now but I think I really have to wait for March 1st for the new plate.
