Which open source cms has the most extensions ?
I am interested in a complex, mature and admin friendly cms. I am also searching the one with most extensions, packages, add-ons ... 

I found these to be the most popular: alfresco, drupal, ez, joomla, dotcms, plone ...

Can you help me find the one I am looking for ? (dotcms and drupal are on my mind now)

Thank you.
