I would like the R's 4WD for the extra traction it gives and the extra power (if I didn't have a remap), but I honestly prefer the looks of the GTI. If you get the right colour/wheel combination, I think it looks racy and classy, whereas the R 'only' looks racy.
I think they both look very classy. The R looks a bit more racy due to its even lower ride height and those wonderful LED running lights. O, and the R is more snow and ice friendly.
However, I totally agree with you regarding wheel choice. I have now come round to the fact that the nicest wheels are those fabulous 19" VWR ones on Ess_Three's and NeilGTi's cars. The 19" do make a visibly positive difference. IMO.
Unfortunately, I won't be getting any as I live in pothhole paradise. The 18" Monza Shadows have just about survived with a couple of near misses - one big one today!
However, two things that please me greatly are that: (a) my GTi will provide better fuel consumption than the R especially in London traffic and (b) my GTi's boot is much more practical and hence more useful.
But I still hanker after an R.
I can dream, can't I?
