depends, id go for one with my toys on it, high spec GTI then low spec R32, but if the R32 has shed loads od extras, then go for that, one thing though, prepare for higher fuel usage, much higher road tax,and insurance group is 18 and not 17 as the Standard Gti. The golf Gti is better if you add more to it, if it has sat Nav , leather , xeon lights, luxery pack etc or if your a family man and have kids, a 5 door is essential, then get the Gti.
hope this helps in such a important financial decision.
