I personally will never use nextcloud, it is nice interface side but while I was researching the product I came across concerns with the security of the product. Those concerns have since then been fixed but the way they resolved the issue has made me lose all respect for them as a secure Cloud solution.

Basically when they first introduced encrypting folders, there was a bug in the encryption program, and the only thing that ever would be encrypted was The Parent Directory but any subfolder in that directory would proceed to not be encrypted. The issue with that is that unless you had server-side access to view the files you had no way of knowing that your files weren't actually being encrypted.

All this is fine it's a beta feature right? Except for when I read the GitHub issue on the report, they gaslit the reporter who reported the issue saying that despite the fact that it is advertised as feature on their stable branch, the feature was actually in beta status so therefore should not be used in a production environment, and then on top of , the feature was never removed from their features list, and proceeded to take another 3 months before anyone even started working on the issue report.

This might not seem like a big deal to a lot of people, but as someone who is paranoid over security features, the projects inaction over something as critical as that while trying to advertise themselves as being a business grade solution made me flee hardcore

That being said I fully agree with you out of the different Cloud platforms that I've had, nextCloud does seem to be the most refined and even has the ability to emulate an office suite which is really nice, I just can't trust them, I just ended up using syncthing and took the hit on the feature set
