If you are looking to have the ultimate helmet for supers as a striker, look no further than the helm of innermost light. You get Death from Above standard and can add another perk to modify the super further, such as aftermath. It is amazing. If you are looking for something that makes you heal a lot and hard to kill, go for the insurmountable skullfort. It regens health when you pick up orbs and when you use the storm fist to kill an enemy, and you spawn with storm fist ready to go.
