A heavy armor with 50 hitpoints is more likely to be hit than a light armor with 10 hitpoints.
What is not known, is by how much, or what happens when you compare 1 50Hp component against 5 10Hp components.

Higher hitpoints act more like armor, but volume does as well.
Something like comparing a bullet proof vest to 25 people trying to jump in front of bullets for you.
