Overall, FreeFileSync is more like Unison [1] than like Syncthing or rsync. Though, I haven't really used rsync, so I can't make a detailed comparison. Syncthing is automated/daemon, so the syncing happens in the background automatically. FreeFileSync's default behavior requires manual start/stop of sync jobs, though it does have an optional real-time sync feature. The main advantage of Syncthing is that it supports multiple hosts/locations for the same backup, and that syncing is P2P between the hosts.
