This is a debate that we often come across in Developer community. I recently started using Joomla, to see what goodies it have. I am primarily a Drupal developer and no doubt I love Drupal above other open source CMSes.

Some of my own findings, as much as I know Joomla by now are

#  The installation process in Drupal is flawless, as compared to Joomla.(my personal opinion )

#  Multi-site installation support is missing in Joomla

#  Joomla supports Mysql only

#  Single-sign on for multiple Joomla sites, not possible.

#  Clean URL support not available out of the box (bad for SEO)

#  For social networking and membership driven sites Drupal is better. Drupal has more granular access control system. The Organic Group module in Drupal adds great possibility to a community driven site.

Just now I came across an interesting post, a survey on the same topic, which seems interesting. The survey is done by Adam Zabzdyr( Webology eBusiness Solutions). In the survey, they have included many aspects of these two CMSes. They have interviewed both Joomla and Drupal users, administrators, Managers and Developers. They even included average budgets of these CMSes and Client satisfaction.

See the 54 page long survey statistics in this PDF file.

But the missing thing is that, they haven’t mentioned a clear cut result on who wins the race !!
