Joomla has Gloss in spades, gazillions of themes, flexible block presentation, WYSIWYG editing, and more flash based presentation galleries than you can shake a stick at.
Drupal seems to have the guts that Joomla lacks; everything integrated, taxonomy, flexible hierarchies, access control, etc.
I'm not saying that you can't have these guts in Joomla (if your willing to code hard) or the gloss in Drupal (can't see how to get this out of the box) but you really do need to choose horses for courses.
