Good question! A lot of our users like how easy it's to start using PerfectWiki compared to OneNote. Secondly, we have much better integration to Ms Teams. Lastly, we have ability to lock content from editing and powerful full-text search.

Many of our new users surprisingly migrate to PerfectWiki even form Confluence :)

Not sure about the content locking, but OneNote is super easy to use, can be embedded into teams tabs or files, and has full text search. What’s better about this than embedding OneNote?

Thank you for these points. I also noticed export to Markdown. Exporting to usable formats is definitely a sore point for OneNote, especially the web version.
