Tough one...
Best all rounder? Yes, definitely. Comfy and relaxing on a run, Still reasonable fun on the twisties, quick(ish), decent loadspace - loads of plusses, but...
Most fun hot hatch I've owned? Nope. Previous hot hatch experience has been with Astra's. Firstly an Mk4 SRI 190 Turbo which was (in my opinion) more fun to drive "in a spirited fashion". This was followed by a Stage 1.5 Mk5 VXR running close to 300BHP and this was like the SRi Turbo turned up to 11. People slated the handling but it just made it so entertaining to drive, whereas the Mk7 GTI (even with the tuning box on it) is very very good, but lacks that little bit of involvement that's required when the car has the tendency to be a little bit wayward.
That analogy almost feels like some people quote when they compare the GTI to the R. People find the R very very good, but some feel it lacks as much involvement as driving the GTI does - maybe?
