Confluence isn't particularly complex, but its per-seat licensing model can get expensive pretty quickly. Operationally, though, it's very much a 'fire and forget' kind of thing: other than applying regular updates to it, I don't have to touch our internal Confluence setup for work much at all. On the other hand, that installation is $2800 to start for a self-hosted instance with 50 users, so it ain't a cheap option if you have more than 10 users. For a group without a budget, I'd lean more towards Dokuwiki or Mediawiki, both of which are still fairly easy to administer and feature-rich.
