I’m running Disqus on one of my site and JS-kit on the other. I agree JS-kit seems to confusing to a basic user and to get all the bells and whistles you have to pay.
I like with Disqus, I can easily post something and have the option to post it to my facebook and/or twitter account.

If WP comments had facebook and twitter integration (the plugins to do this, never seem to work right) I’d stick with them!

With WP owning ID it will be interesting moving forward.
