I'm not sure if any are really "the best." I think they all have their issues, and it's just a matter of learning the foibles of whichever you use and accounting for them. I personally use BeerAdvocate, FWIW. I'm also on Untappd, but that's more of interest for seeing what other people you know are drinking (whose taste you trust) than aggregating reviews from strangers.
