Core MediaWiki. Vanilla. It is A LOT closer to that because if no longer has to worryabout the custom code mess of Forum, Chat and Comments. By moving those elements off of MediaWiki, the wiki itself grows closer.

Wikipedia uses Vanilla because they are the Wikimedia Foundation. It's build for their needs. Miraheze is so tiny it doesn't have phabricator access, and not enough engineers to swim anywhere but the kiddy pool.
