Confluence is pretty good. It's better than MediaWiki, the Wikis built into GitLab (or GitHub if that's your thing), etc. I dislike that it doesn't support MarkDown as a native language, but it does have a solid WYSIWYG. I'd say Confluence is the best of their products and the one that I'd be most likely to use again in the future. I've also used their CI solution at another company and I found that one easier to use than most of the other open source ones, although I haven't tried some of the newer ones in the last few years or GitLab's CI integration.
