Almost any issue involving durability between the two is negligible. Outer tubes of either one should be steel, both will be mounted to action and barrel well. If there were any genuine concerns about breakage of the follower it would be shipped with a flexible one. Since the Henry has a loading slot, if there were concerns about losing the follower, a dead simple lip on the road and retaining bolt on the tube would lock it in place.
Judging by my own tube fed rifles, gated and otherwise, I can see no concerns for either system, they are both subject to the same damage, both have the same strengths.
We could look at tube fed shotguns, and notice that for a variety of reasons, they are all gated. That brings up one of the only benefits that I have ever seen for a gated magazine. A person can sit on a duck blind, fire one of three rounds, and replace that round with minimal hand movement, leaving the gun in place.
