Vog vs Grey Feather

Hi all,
Sorry if this has been asked already, I have tried looking ~
My current loadout is:
Grey Feather Mantle with high piercing UV
Elemental Hood with medium piecing UV (soon to be Grey Feather Cowl)
Brute Jelly shield with medium elemental UV
Piercing trinket
(I should prolly get a shadow trinket tbh)
I havent bound yet:
Dusker Cap and Coat with medium piercing UV
I am wondering if it is better for me to sell the dusker set, as I only gain sword dmg whilst losing shock resist ~ and without trying it, I dont know how much extra dmg I would gain with a vog setup... also, I like being a little bit different, but not suffering for it :`)
Also, I am finding it hard to guage how much a dusker set is with medium UV ~ my second week into the game!
TYA!
