I think the distinction between them is that a chain stopper is to hold the strain while anchored and the chain tensioner is to tighten it up to prevent rattling while the anchor in stored.
In either case the picture you posted of a stopper doesn’t look substantial enough to use on your boat.
All the best,
As fast Cam points out some nylon line or rubber snubbers in the system is worthwhile to take the jolt out while at anchor. Boy, you need to get up early in the day to beat Cam to the keyboard.
