"TYPO3 seems to only be a web content management system, whereas eZ Publish is first of all a content management system"
Our web content management system features is part of the webin extensions witch is installed if you select the Webinterface or Flowinterface package during the install. I personally always build on top of them, but they do add another layer you'll have to deal with, so can be a bit more difficult the first few times.
