MODX has a very flexible and robust architecture for user roles and content access. MODX lets you serve up roles-based content very easily, and its sophisticated caching gives you a pretty good performance trade-off. It scales well too, although Drupal remains the king of scalability in this field. MODX has been very well architected so that you can build on top of it very quickly. That is not always true of Drupal, Joomla or WordPress. Drupal does benefit from a very long list of contributed "modules" to extend the system. But if you think you may need to do things which are not already built into the CMS or offered as an add-on - or if you are not enthusiastic about Drupal's steep learning curve - MODX Revolution may be your best bet. Documentation is light, but the MODX community is highly responsive and helpful.

Customizing ModX is easier compared to traditional CMS. The framework is flexible and adapts easily to changes.
