Drupal vs. Joomla vs. Mambo vs...

[tennis_bear]

I've been tasked at work to evaluate Drupal vs. Joomla vs. Mambo vs. (any other credible, cheap PHP-based CMS I can find).

If you have hands-on personal experience with any PHP-based CMS platforms, I would be most appreciative of anything you've got to say about them, good or bad.

Thanks much,
