CMS with good 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.

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.
