VBulletin is superior in function, but it's a barrier to entry for new commenters. Most people visit multiple sites and new visitors may want to comment but don't want to sign up for registration to yet another site. Disqus lowers the cost of initial participation because people can login with any number of IDs they most likely will already have. Also, VBulletin doesn't seem to be updating, but Disqus will most likely evolve through continued development even if the features are somewhat barebones at present.
