I use owncloud infinite scale and overall its rock solid. The downside is the lack of plugins. Nextcloud has been nothing but trouble for me and every update was a mess so I decided to try OCIS and for my need I was extremely satisfied.
Now, I admit, I’m not one to get carried by the drama in the FOSS sphere (still use Gitea) but I do agree there is an history to the separation of owncloud and nextcloud that can make some people uncomfortable. Having a choice is good I believe.
One of the first interaction I witnessed from the forgejo guys was this PR:
https://github.com/go-gitea/gitea/pull/27455/
The interaction and stubbornness of earl-warren felt like it was just that, provoked drama.
