CMS with best administration part?

Hello, I'm looking for CMS that have great administration part. I'm not interested in site displaying, speed, HTML standards or anything like that. I just need stable administration part with modules: - News with archives; - Blogs; - Some users Can be administrators of blogs; - Link directory; - Navigation with multiple categories and subcategories; - Different news for different parts of my web site; Web site will be very large and it will have almost any module that you can find these days :) I like XOOPS [1]. I also have my eye on Mambo [2]. A friend of mine told me that Drupal [3] has best community and if not drupal that I should check EZ [4]. What do you think? Which CMS has best PHP coding standards, best community, most modules etc... Any advice is appreciated. 1. http://xoops.org/ 2. http://mamobserver.com/ 3. http://drupal.org/ 4. http://ez.no/ If you know of some other CMS please send link. I know of opensourcecms.com but I'm interested in your opinions about project future, community etc.
