Owncloud/Nextcloud... beware. It's significantly worse than the other services. I've tried really hard to make it work (including self-hosting), but it's just poor software, for a few reasons. Worst problem, which I haven't experienced with the other services, is that if there is a connection problem (this may happen routinely, if servers have scheduled downtime), files may go out of sync. Result is that, ridiculously, one may get conflicts even if they're using a single client in total. There was an issue opened, which has been ignored and autoclosed for a while. Second, lack of centralization causes a bit of a mess. One never knows which version the servers ship (although one may not care); hosts may be less realiable, and finally, hosts may change frequently (I've see a few changes in the list of free servers) so one is never sure how long the service will be offered. Also, the configuration shipped with the Nginx version was not great. Overall, I think that the software "isn't great", and I don't trust it for personal data.
