The answer can only be found in what you want to do with your site.

If you want an all in one, integrated what not, you need a CMS. If you want a blog, I’d say you want WordPress (or similar). Functionality is the name of it all. Sometimes you find a tool you love so much you’re willing to forgo integration for features. Other times you decide you have to have it all be on. I’ve run Drupal, WordPress, bbPress, Gallery, PostNuke, PHPNuke, phpBB, SMF, InvisionBoard, MediaWiki, and more. They all fit the needs I had for the site I was designing at the time.

Figure out what you want to do, and what will be more important. If you have to have native integration, use a CMS. If you don’t, then your choices are infinite.
