title: Zend vs drupal (comparison)
body: <p>We have a project to build a web application that has many features like: google maps integration, item review and rating (something like eBay rating), chatting among users, content search based on content calculated value, integration with Facebook (for login, liking the content, fetch user's friends...etc),batch and real-time notification through SMS and email and many others.</p>
  
  <p>We have two candidates for this zend and drupal, I tried to search a detailed
  comparison between them without luck; only found high level stuffs.</p>
  
  <p>Our criteria is to use a product which will not require lots of custom development and satisfies most of out needs out of the box, and it should be reliable and easy to maintain and extend in the future.</p>
  
  <p>I would really appreciate if someone can shed some light on zend vs drupal comparison and point me to any useful recent analysis already done in this. </p>
  
  <p>What are the real strengths of zend ?</p>
  
  <p>Thanks in advance and best regards</p>
