PC on Eternal Bow and Storm Bow

Got these 2 bows:

Sundering Eternal Bow of Fortitude (non-inscr)
15-28
req 9
Energy +5
20/20 AP
+30 HP

Vampiric Storm Bow of Deathbane (non-inscr)
15-28
req 9
5/-1 Life Stealing
Dmg +20% (vs. Undead)

I personally think the last one is very good for barraging undead (Barrage+Judge's Insight) but I don't know the value of both of them.

A good PC would be appreciated

if the last one has no inherent mod, it's pretty much worthless, unfortunately. salvage mods if you want and merch
