I recommend against Drupal due to its inefficiency. Yes, it can do almost anything, but it does it slowly. For any but the simplest of sites, drupal will not build nearly as efficient a chain of queries and pages as a custom built site will. Something that can be done by hand with two SQL joins and a single PHP loop is likely to be handled by Drupal with five joins and a nested loop.
That said, I love Drupal and will continue using it in non-enterprise environments, and I cannot recommend any other CMS that does not have similar problems when presented with complex tasks.
