Recommended Comment System?

Do Grav users have a recommended comment system to use with a blog? Something that can be used in development (localhost, not remotely accessible), testing (a staging server that is accessible), and production?

Disqus, Intense Debate and LiveFyre seem to be the front runners. In some ways they seem very much the same. In other ways, not so much.

I've personally used them all, and my favorite used to be Intense Debate, but I've more recently switched to Disqus and prefer it. Faster, cleaner, and looks better.

Does Disqus do OK on a local development server when the Disqus servers can't reach it?

Yah, works fine.

Thanks, that's where I'll go first, then.
