    For those who prefer FOSS, Nextcloud is the way to go. ownCloud is partially proprietary so they have a different philosophy.

    Seafile is a more focussed, nimbler sync & share solution compared to Nextcloud (and the original ownCloud) that excels in performance and stability.

    I tried NextCloud and it was very hard to set up permissions in a enterprise environment. Seafile is simpler

    NextCloud is groupware. Seafile is a file-sync storage solution. Just because they have overlapping functionality, does NOT make them interchangeable.
