wordpress vs drupal vs joomla...
Joomla is current Trend.
I know that this is not really anything new to a lot of people that have been using joomla as a CMS only.Joomla CMS has better security and can be build with good quality

Joomla and Drupal are two magnificent Open Source Content
Management System which provide the framework to develop
effortless with various ready to us modules and website in
short span of time.

Main differences are as under

1. Drupal use smarty template where as on the other hand
Joomla dose not

2. Joomla uses plugin and modules whereas Drupl has module only

3. In drupal php code can be written directly whereas in
Joomla you need to install plugin for php support
