I hate Dropbox for different reasons, and switched to ownCloud about 4-5 years ago now, I think. Running it on Digital Ocean, and backing up to Tarsnap. Absolutely love it. I get that it's not for everyone, but it's really not that hard either.
I started using ownCloud before Nextcloud was forked, and NC seems to have evolved to do much more than just file syncing. However, I don't care about any of that, so I didn't see any benefits in migrating. I actually like that OC is focused on file handling. "Do one thing well" etc.
