Anyone trying to evaluate open source content management systems is aware that there aren't a lot of recent, useful comparative reviews. What's surprising is that this issue is true even for such popular solutions as Drupal and Joomla.

Stating in January that, "most comparisons of Drupal (news, link) and Joomla (news, link) conclude that you should select the one that best suits your needs. However, they give too little guidance about how to do that," Webology eBusiness Solutions set out to quantify the pros and cons of each by releasing a survey.
The Survey

The survey divided questions into five categories:

   1. Developers
   2. Documentation
   3. Performance/Functional Aspects
   4. Appearance
   5. Ease of Use/Learning

Users were classified by their response to "CMS most experienced with," with those answering "Not Applicable/Don't Know" to this question being removed from the analysis.

In general, the respondents were slanted a bit more toward Joomla users than Drupal users. Their roles when working with their respective CMS's break down to the largest group being Project Managers, and other large groups including Programmers and Designers. The Drupal users were, somewhat unsurprisingly, more experienced, with a median of 7 years experience in web development, while Joomla users claimed 5.
