Nextcloud on Hetzner has been great in my experience. Running for a few months now as a Dropbox replacement and very happy. Mobile app, mac app, it all seems to work exactly as expected.

My only gripe is that they do not allow Nextcloud external storage[0] but that's understandable given what they're selling.
