My only gripe with wiki.js was the use of SQL for local storage. My wiki must be future proof and locking myself in an obscure SQL database was the deal breaker. I know that you can sync with a Git repo, but it felt like an overkill.
+1 Dokuwiki. It is a little complicated than most to configure the first time, but once you have everything running, it will work without complaints. Also, the whole wiki is stored as plain text files, which is awesome for backups.
