The trouble with most reviews sites is the signal to noise ratio. Some are better than other, of course. But, if you're after some names, webhostingjury.com, hostjury.com, webhostingunleashed.com, findmyhosting.com and webhostingreviews.com would be some of ones I know of.
Haven't tried webhostingjury.com but hostjury.com doesn't seem to work properly and seems a bite bias IMO. findmyhosting.com is a bit shady due to most of the big players winning they're award. Just seems like they make it less obvious. webhostingreviews.com I haven't tried so no opinion at this time. webhostingunleashed.com is a perfect place to find customers that are very upset with they're current host. If your good, you might just be able to turn they're situation around for them *hint *hint.
whreviews.com does a great job and is highly recommended along with hostdisciple.com and whreviews.com and are the most trusted.
