Pearl Izumi shorts = 5.0 - 6.0 depending on style
Voler shorts = 8.5
Voler bib shorts = 9.5
naked = 10 
Pearl Izumi makes some very nice bib shorts, although they can be very spendy as well. They do seem to last a fair amount of time and are comfortable. I prefer them over Voler bibs, but that is just me ... I have a friend that can't stand the way Pearl Izumi fits and swears by Voler.
For a truly divine, yet truly spendy experience check out Assos's bib offerings!
