Which is better for EE, Storm Armor or Magic Wep Electrify

I’m currently at 25% crit. I was thinking of Switching to Storm Armor [Shocking Aspect] from Magic Weapon [Electrify]. for my lightning dmg in my Elemental Exposure build. Its hard to tell which one is actually doing more for me. I’m thinking about waiting till being around 35% crit chance to run Shocking Aspect. Though I am running fire disintegrate over fire blizzard, and there is a lot of crit potential in disintegrate to just machine gun out lightning.
