Feed reader

I know this conversation has gone on before in the Cat Blogosphere, but we've been getting behind on keeping up with our friends' blogs and I wanted some opinions... I've set up Google Reader in the past, but never got in the habit of using it (honestly, it seemed that I could read the post, but then still had to go visit the site to leave a comment and I think that's why it never caught on for me).

So my question, which reader do people seem to prefer? Is one dramatically better or easier or more convenient than another? I want to find an easy way to keep tabs on everyone and not miss and be able to comment more efficiently ... (really, how DOES Daisy visit everyone?)

Thanks for your input.
