I realise that I'm likely to get a biased report from here, but I'll ask anyway - how does Drupal stack up to Mambo? What are the advantages and disadvantages? I'm looking strongly at either Drupal or Mambo as a solution, and I don't want to invest time and learning in a CMS I won't end up using long term.
The website is going to be mostly information rather than community (so no need for forums, comments, etc). It is for an educational institution, including course information and other details like that.
