Hmm the review site you mentioned looks sham to me (someone must have been paid, hopefully a lot, to come up with such reviews & ratings).
The top-rated Wiz Web Host currently has PageRank of 1 instead of 7 as claimed.
And some of these "reviews" even look like advertisements in disguise.
IMO, most review sites are just paid marketers for hosting providers, in order to get the bigger picture and protect your investment sometimes you have to google (search) negative user reviews on the web, like this one:http://www.diagnose-...ucks/lunarpages.html
which tells the stories of former clients of a "Rated 90 out of 100, PageRank 8, definitely a choice of web hosting" web hosting provider.
