I remember a review a few years ago the result of which was that they're all pretty good. Maybe the cheaper ones are more likely to fall apart, but optically they were much of a muchness.
I tried a Hoya Pro series polariser the coating of which proved very susceptible to getting scratched. Even sweet wrappers in my pocket would do it. Hoya replaced it for me but the second one was just as bad. I suggest that a polariser will be on and off your lens so often that it needs to be a bit more robust than that. I went back to the standard Hoya ones, which have always seemed fine to me.
