I found that Twitter Bootstrap has better looking defaults after using a morning caffeine burst to drop Zurb Foundation into my app and see the difference. For example, things scaled much nicer on Bootstrap when I started Ctrl-MouseWheeling the text size. That said, I hope Bootstrap 2.0 nails responsive design. I think we should be checking our progress on mobile devices as we develop, not drop in a mobile solution at the end and hope it works. Responsive design is the hard part whereas look-and-feel CSS is more trivial to drop in.
