Coup.
I'm tall so I usually have the seat back all the way and in most sedan's that puts the B pillar right next to my noggin. Not only does this create an odd blind spot, but it makes it very uncomfortable (see "impossible) to rest my arm on the window ledge.
They usually look cooler too, but for me its more about the ergonomics (damn that word makes me feel old).
