Like with most any survey anywhere, especially a "best of", it is pretty easy to get skewed results. Depends on how hard a place pushes to get votes, how much promotion they do, how much they push their employees to push for votes, etc. Like with reviews, take it with a grain of salt. Use it as a tool when making a decision but I also know many reviews I would not agree with.

What I consider the "best of" anything may be way different than you or anyone else.
