If you're a completionist and want all the Daedric stuff done, you're going to have to give Umbra up eventually. And the perfect madness sword isn't that attractive looking.
So, Goldbrand 4LYFE.

I normally use goldbrand for its high damage and since its weightless I use umbra aswell. I only use umbra for recharging gold brand and for when Im out of magicka

Goldbrand
