I would highly recommend nextcloud over seafile. Seafile does not appear to take security seriously in any capacity as can be demonstrated by the maintainers here: https://github.com/haiwen/seafile/issues/350 , https://github.com/privacytoolsIO/privacytools.io/issues/490

Nextcloud is written in PHP an so many people believe it to be insecure per default, but the devs are highly capable and put an emphasis on security from my experience.
