Well, the Rhino in that second screenshot looks like it's affected by the Corrupted buff that you can occasionally get from Fissures, so you've got doubled Strength and Range on that and that'll affect Iron Skin's multiplier. Not a very common circumstance.

Since you keep armour stacks while Iron Skin's active past the invulnerability stage, and that companions seem to allow you to pick up more health orbs to keep Health Conversion maxed, I can see Health Conversion giving a pretty consistent buff over Steel Fiber. Even just one stack would give more armour, come to think of it.
