To Drupal or not to Drupal?

One of the things I'm currently considering is a new CMS system. I have to pick one out for a site I have to work on and finish with a deadline of about three months from today. The obvious ones that come to mind are Joomla or Drupal. Both are free CMS's, customizable and efficient. The finer details are what set them apart, at least to my knowledge.

I am on the lookout for a good Drupal tutorial for the beginners in Drupal, or something of the sort. If you know any good ones, drop me a link in the comments.
