The biggest benefit is you get to use Notion for the backend content creation. It is prett different from more traditional WYSIWYG editors like Wordpress’. I think for smaller sites including in some collaborative instances, Notion makes more sense than Wordpress. Of course Wordpress makes a ton of sense in so many ways. Including for most collaborative scenarios.

Mine is a hippie ish free organic growing virtual coworking community. So it is easier to get active members to add to Notion than Wordpress. I think this is an edge case though.
