Free advice -- worth what you paid for it: for sites who don't get many comments, it doesn't matter what they use. For those that get lots of comments, the two most important things are building a community and moderating it. To a large extent, community depends on history presented cogently. To that end, showing a user where they are in a thread and what they haven't yet read is paramount.

Build distinctly better moderation tools, and the experience will be enjoyable, too.
