I drove both and favoured the Leon and bought a Lunar Grey FR TFSI with
18" wheels. The Golf's are very common (but a v.good car) and the rear of the car is a real let down in comparison with the Leon. You definitely get more looks in the Leon and it has a more muscular/quirky/sporty look from all angles which appeals. There are lot's of subtle styling points aon the Leon which set's it apart such as hidden rear door handles, mock rear diffuser and stalk like wing mirrors.
Yes residuals won't be quite as high as the Golf but you haven't paid as much to start with but they are still not bad at all.
Gotta go for a Leon over an grey import Golf, you'll know what I mean when you go to sell it...
If I had the choice again I would buy the Leon again even with it's hardish ride, I'm a converted
badge snob and happy with my choices...
