I was quite set on a Prius when I first started researching. But when it came down to test drives, it was pretty close between the Prius and the HCH. I went with the HCH because I didn't feel as cramped, or closed in--I felt like I had more personal room in the HCH. Well, that and the fact that I liked the displays better. I'm 6'1, btw. I don't know about specific seat adjustments in the Prius, so someone else will have to chime in about that...
