MailChimp API recommendations?

This page - <http://www.mailchimp.com/api/downloads/> - lists five
gems/plugins for interacting with the MailChimp service, and for all
I know there are others.

Anyone have a personal recommendation? Based on any of stability,
ease of integration, completeness, whatever...

TIA,

I've been using Hominid for a while (http://github.com/bgetting/
hominid) without problems, it is up-to-date with MailChimp API last
version, and development is active
