Django or Drupal, which one should I use that suits best my needs?
Jump into what you like or what attracts you most after getting a little overview of the capabilities and constraints. I never worked with drupal, but I can recommend django.
I want to learn and use Drupal or Django for the following: 
dynamic web sites, medium database, multi-level users, paypal integration, content managment, speed (developing), security 
I like MVC, ORM and object-oriented prg.
Which is better to jump into ?  Which one is more mature, powerful, understandable, object-oriented and easier to use by the time ? 
What about Python Spring ...  
Also, which of these 3 are better documented, are better for a cv and have more extensions?
Known languages: php, java, mysql
Thank you !
