For building sites or for building apps? While Drupal can be used to build a great web site for a company (and often is!) Joomla's extensibility seems aimed more at rapid application development using a strong mvc framework. If you don't mind relying on 3rd party contrib modules and external development roadmaps, you can build apps in Drupal, but if you just want a framework to build and deploy your own web apps Joomla is fully extensible in the OOP sense. Also Joomla is classier than Drupal. :-P
