XenCarta is a minimal wiki, and if you end up needing something complex it will not work well.
VaultWiki is a full-fledged 'native' wiki however it is prone to bugs; it does have some features that are impressive such as the templating and variables features. I've tried to use it several times, and it just ends up being too problematic to use.
I've attempted to use Resource Manager as a guided page generator for wiki-esque pages, and it's too limited to work well.
I've also used Showcase in the same manager as Resource Manager, and had much better results but there are still limitations.
ThemeHouse had a MediaWiki bridge, however I am not sure if it is available or supported any longer. I've also considered having something made, however I do not know if I will use MediaWiki or look at another solution.
