Preference order based on looks:
1. Gran Coupe
2. Msport Sedan, Sport sedan
3. Sport Wagon
In terms of utility and space seems the numbers may be misleading.
The very sloping rear roof line of the GT and GC appear to take away usable headroom for rear passengers.
The chart shows a decent number but it's measured way forward of where a passengers head would be.
Maybe the rear seats are very reclined so that rear passengers heads clear the roof?
But that could mean an uncomfortable seating position for some.
For best utility I would think the sport wagon would be the best fit, but then I haven't sat in a GT or GC.
