I've been studying what Consumer Reports has to say about both, and the Fit seems universally better. Quieter, better acceleration, handling, and turning, cheaper, newer, from a more reliable company, and prettier. I'm also small enough that the Fit is plenty comfortable. But you do have a point.

But seriously, xB and xD look like they're just naming their cars with smileys. I blame zhukora1 that I notice this.
