Maybe the GTI clubsport is the best all rounder.
GTI looks with a bit more power if needed. No four wheel drive but a lighter, nimbler car.
Or maybe I'm wrong 
No I think you're right.
Just a shame it's a bit ugly from the front. Too many angles going on.
From the driver's seat I'd imagine it was by far one of the best cars out there that VW have ever made.
*************************
For some reason I think my R rode better than any of the GTI's I've driven in that although it felt a bit more hefty it didn't crash over sharp ridges in the road which every GTI (and GTD for that matter) seemed to do.
If you're 'on it' then obviously the superior traction and top end power of the R trumps the GTI hands down. Looks wise it's 50/50 with the R looking lower and meaner in a discreet sort of way and the pre FL GTI looks a bit prettier, especially in lighter colours with the red accents giving it a bit of contrast.
I'm not overly sold on the looks of the FL cars in any of the pics I've seen, or vids for that matter. The frontal styling has just got a bit too busy for me. I can understand why VW did this and I don't dislike it, but I'm just not sold on it, preferring the simplicity of the earlier mk7's. The rear of the FL cars looks a bit better.
My R was quite a thirsty beast, but probably no worse than my mk5 GTI and my mk7 GTI one of the most frugal petrol engine's I've ever owned. The easy going and very flexible power delivery of the GTI made it feel a bit flat at times where the R comes alive over 4000rpm. So I guess it depends on how often you use over 4000rpm because there ain't much between them below that point.
Inside? The GTI has a bit more panache to its styling but the dials in the pre FL R are absolutely lovely. I also found the seats in the R (non leather) to be amongst the most comfortable I've ever sat on/in. Being as it's basically exactly the same seat as a GTI/D then it must be the nice alcantara bolsters that are so grippy.
Ask the same question on the R forum and prepare for the incredulous comments about how the two names should never even be mentioned in the same breath!!

(and they'd be absolutely right if you lived somewhere with no speed limits)
