Cantilever will retain zero better, so long as you get tension on the cap the same each time the barrel is installed.
Receiver mount will always have a little more 'wandering zero' effect; since the barrel is not affixed to the receiver, but is merely held in place by the magazine tube.
Unless you like using your shotgun as a pry bar, shovel, hammer, or base layer in a pile of tools and garbage behind the seat of your truck, durability of the two types isn't really worth nitpicking.
