I decided the Sedan ages ago (at the motor show), but when I actually saw them in person at the dealer, and was allowed close up to them, the hatch really did grow on me a lot.
Still went for the sedan in the end, but it was a close thing. The main thing was that I didn't like the angle of the hatch itself - too oblique, looks a bit too much like a people mover.
The plus side of the hatch, though, is the rear window wiper on the hatch, which you don't get on the sedan.
