On the CMSMatch.com site there's a new post with a "top ten" list ranking some of the popular content management systems:
CMS Match collected data on CMS functionality categories, such as core apps, flexibility, interoperability, mobile internet, performance, security and available support. The available functionalities are scored for each CMS. For example a blog functionality. Scores range from not available (0 points) through limited (5 points) to fully supported (10 points). Based on these scores, CMS Match was able to calculate a top 25.
