how accurate are the site reviews on pokerlistings?

I'm checking out the pokerlistings.com site and they have some reviews on each site. They rate the level of competition on a scale of 1-10 (10 being easiest), as paradise a 2, pokerstars a 1, and party poker a 7. But they also list Bodog and Titan Poker as an 8. The hell is going on here, seems rather subjective, so I guess party doesn't have the most fish?
