Counter-argument! I actually like the HB, but only by a slim margin.
To me, the sedan does have a less abrupt rear light design. However, I feel that like a Corolla, the design is too "safe" and I'm concerned that it won't age well. Although the HB has a back that can be unappealing at times, I also find it more interesting. The sedan is still a pretty machine though.
I grew up with a both a wagon and a sedan. I loved the wagon for the accessibility of the trunk, and hated the sedan for the smaller trunk opening. Many times I wanted to carry something big and bulky, that should fit into the trunk/interior, but doesn't simply because it wouldn't go through the opening.
Finally, I like the more aggressive stance of the HB.
