Comment systems for Blogger

I have seen lots of people complaining that the comment system of Blogger is crappy and I do tend to agree - not only is it quite simplistic, you cannot leave "threaded" comments (this is important when you want to interact with your readers).

As far as I can see it, the four choices when dealing with Blogger comments are:

1. Keep generic Blogger comments + wait for them to implement something good
2. Use Facebook comments (good tutorial here)
3. Disqus
4. Intense Debate

I have used Disqus and am currently using Intense Debate on my personal blog.  Everyone complains about Disqus (not exactly sure why, I must admit it has always behaved for me) and Intense Debate has so far worked out well and is quite adaptable.

Facebook.... well, I am not sure how I feel about Facebook comments.  I dont think so.

Disqus is nice because you can back up your comments - so if you ever want to remove Disqus, your comments will be hiding underneath.  Intense Debate, as far as my research tells me, does not offer this.

So, what do you think?  What do you use?

PS: I am not really going to even give Echo a mention.  Whilst they look like a pretty rad comment system, I don't like their exclusivity. They told me that I needed over 1 million hits a month and quite a hefty yearly fee (I am talking more than just a few thousand dollars here).

UM NO. JUST NO.
