File syncing is the one service I can’t do without, and I critically evaluate whatever tool handles my syncing. Over the years, I have used several, but I keep going back to Unison, one of the first syncing tools I ever tried. Unison delivers syncing in ways that even newer apps don’t. It doesn’t have the polish of tools like Syncthing, but it still works like a charm. Unison is not dramatic. Once you sync, everything is up-to-date without delays from cloud routing, queuing, or third-party uploads.
