I like them both on principal, but GetSatisfaction needs to remove forcing your users to sign up to leave a comment! Should be no barrier because if there is Im gone and would say those who felt compelled to say something are too.

Depending on what you're using it for, there's also our featurelist.org -- which is free and lets you export your data out if you so desire.

I think this might be a little more what I was looking for. I will have to sign up.
