For the sake of a nice sound id rather get a 1.8T and leave some money aside to remap it (remap is a MUST if you get a 1.8T) and a full turbo back Milltek system (at least you get a nice sound, its not a V6, but still sounds nice). If you drive a sensible amount of miles you will make your money back in petrol in no time, especially the way prices are going at the moment.
Depends what your funds are like and how much disposable income you have really.
