I really dislike wordpress, and Joomla isn't much higher on my like list, tbh. Drupal is sometimes a pain (it was a REALLY steep learning curve for me) but newer versions are easier to use and I imagine it will get even more intuitive and user-friendly as time goes on. The one I hear praised a LOT is modx.
tbh, no matter what one I try out, I always just come back to Dreamweaver. Perhaps there are some that will argue that Dreamweaver is not a CMS but technically it is and I don't like the others so :P to them, for lack of a more sophisticated way to put it. hehe.
