I need help googling

[Nick J.]

for no particular reason I was curious if there is a publication/company or whatever that grades and compares franchise opportunities among different trades.

I'm not really looking to get into any franchises but for some reason I just thought it would be cool to know who the best franchises are out there and how to know they're the best. If you google(or me at least b/c I obviously suck at searching) anything related, all you do is get a bunch of franchise opportunity websites which of course I know will tote their franchise opportunities are 'Fortune 500' :roll:

any help?
