I think the knowledge of the team is not that important. I would choose the CMS after knowing what I have to build as a new website. Bigger enterprise websites should be done mostly by TYPO3. I have the experience that if I tell bigger companies that I work with TYPO3 I have a chance to get the job. Working with WordPress makes much more sence if I want to have fast efforts, low costs and most all: If I want to have “blog functionalities”. There are plenty of agencies that can setup a bsic TYPO3 installation, some setting with TypoScript … depends on the given requirements.
Wordpress themes come with too many options, JS and CSS to bring much nice features – I can’t stand this source code. Small companies, small associations and so on may work with WordPress … that’s okay …
