Difference in Joomla, Magento and Drupal?

Let me clear what is difference in Joomla, Magento and Drupal Technology?

Magento is an ecommerce suite best utilized when you are set to have an extensive item run (in excess of 1000 items), or require exceptional customization that different Cms + ecommerce suits can't handle.

Drupal is an exceptional substance Cms, yet you need to know your stuff to get the best from Drupal, its not simple to simply pickup and run with. In the event that you're set to utilize Drupal do your homework first.

Joomla has issues, the 1.6+ limb (now 2.5.2) still requirements pleats resolving, at the same time, it is the simplest to work with and there are more artists, planners and programmers working with Joomla than Drupal. 90% of my work is with Joomla and that is not by mishap.

Joomla and Drupal can do everything you require (well very nearly), where as Magent and Wordpress are more particular in the purpose.

Thanks for suggestions
