One thing that it beats the cloud / centralized sync on is because the connection is direct between devices when the initial transfer is completed the file is completely there on the other device. With a cloud type of sync you do the transfer twice. I've seen stack up on large media or with the structure of cloud services pricing making it expensive depending on how your workflow is setup with inside and outside parties. For example, Dropbox deduction from all parties' storage limits not just the sharer.
You can also point Syncthing at a local sync of Dropbox or Google drive and then forward the files to other recipients from that for some purposes.
