I couldn't disagree with you more.
The R is a fair bit more expensive ( £4000ish ) if you buy it outright and spec it the same as a GTI and the performance of the GTI is more than good enough for today's roads.
4 WD is nice but as a few people have mentioned, a good set of tyres is as important.
If you don't do the mileage, the GTD is pretty pointless due to DPG issues.
