Depends on the current content and the weapon progression of your friend(s).

As far as damage goes, 40% element is better if you have good Assault levels. If you don't, then it makes little difference.

And 20% HP is always 20% HP. If the content is hard, then 20% HP is good and can be worth the loss of damage output. If the content is easy, then who cares about HP?
