Best WordPress Comments Plugin

So which is the best WordPress comments plugin? This is a pretty divisive topic.

Comment spam is one of the huge issues any WordPress administrator will face. Personally, I got annoyed with having to deal with it and turned them all off. I am now looking at turning my Wordpress comments back on. My social diary experiment won't work so well without feedback!
