noise, handling, and any other factors are 100% trivial and will be no different whatsoever in these cars (including rear seat room)
the only real difference is styling and cargo utility. Rear seats up, the Sedan's trunk trumps the meager hatch space. Rear seats down, the Hatch is clearly far more cavernous. Do you want a bigger traditional trunk or a cargo bay? pricing difference is give or take a grand. Ultimately I think styling is the most important thing at the end of the day, so which one looks better to you?
