My son is 6'3" and has no trouble with the rear (or front) seats in the hatchback, I wouldn't worry about the sedan vs hatch as far as passenger space goes. I am frankly amazed at how roomy the hatchback is.
SX Sonic has it exactly right though, the Sedan is A) cheaper and B) has more cargo space when you have passengers in the back. However the hatchback is a great passenger vehicle OR a great cargo vehicle, I have fit astonishing loads in there with the seats folded flat, and hardly ever use my F150 anymore. The seats also fold 60/40, so it's possible to carry a mix of large cargo and a third human... but that doesn't work as comfortably.
Finally, as far as looks go, I prefer the hatchback, but I know plenty of folks who prefer a sedan look, there's no accounting for taste.
