I use Disqus for my personal blog. They are really cool people and they're users here on HN. However, I've had problems with Disqus not showing comments after a few hours, and I've since read at least one other blog that has had the same problem. I'm sure it's something they'll fix eventually so I wouldn't necessarily let that dissuade you. I don't have any experience with any of the other comment systems.

It does get frustrating when you have an article with 40 or so comments, and only the last two visible. I like Disqus a lot, but if it simply doesn't work - it doesn't work.
