There is a huge gap between Joomla responsive templates and WordPress. Every day we can see beautiful WordPress templates being development, compare with Joomla templates that came out so little and some of them with so poor quality, compare with WordPress
That is why WordPress is used on most websites you visit every single day. It is very easy to implement on your site and gives a lot of plugins. You can even get a lot of choices when it comes to themes and templates.
And what about Drupal? I searched on the web and found this page: http://www.threehosts.com/wordpress-vs-joomla-vs-drupal.html which confirms what is claimed by both Danrcf and Pusaqall. They say the volume of WP plugins is high, Joomla extensions medium, and Drupal high. I wanna know the comparison between Drupal and WP. Which provides more templates? which do you prefer?
