For what it's worth though, I like Disqus the best. No way would I use facebook comments on an adult site because no one wants their comments posted to their wall, and IntenseDebate is ugly on a site IMHO.

I actually have a site that sees about 10K uniques a day and it uses standard wordpress comments with email disabled so all they have to do is type a name and a comment and it posts. Been running like that for a couple weeks and not a single comment.
