The stopper is a more rugged and foolproof system for insuring the chain does not go "south" with your anchor while at sea. either should be used as a substitute for a nylon "snubber" while at anchor but can serve as a backup to insure no windlass damage if the snubber gets detached.
The tensioner is more useful as a device to eliminate chain rattle on deck.
