What box would hurt more landing on your head?

I theorize that a box with 100 pounds of feathers will hurt less if the feathers are not compressed but loose. The box should have a lot of surface area whichever can give.

A box of metal will transfer most of its energy into the target cranium.
The Crumple Zone effect..... cars do it now a days in car accidents
The longer the duration of impact the less the effects of the force. It's absorbed so to speak. Vs. a Bounce which is bad (for your head/face/whatever)
