Syncthing makes Dropbox look downright barbarian. Especially if you combine Syncthing with Android and a NAS or home server. iOS is... not really capable of sync outside Apple ecosystem. And this is true even with Dropbox. Not an Android fanboy. Just stating the fact. I take a picture on my Android phone and I don't have to think about it. It's now on my home server, it's encrypted, it's automatically backed up, etc. I have an app that takes a backup of my phone and puts it in a single file. Literally I press a button and my entire phone is backed up via syncthing. I use KeePass. My passwords are in sync at all times, on every device. There is also KDE Connect, which I have yet to try out.

Even before Syncthing, Unison existed since 1995. Which was the true free software version of Dropbox. You never needed a bunch of hacks to get automatic sync working on Linux. Syncthing is a bit easier to configure, IMO.
