I just kind of wanted to keep a small list.
Chelsea Wolfe and her band, along with Deafheaven are pretty talented. I enjoyed the shit out of Sunbather, though in all truth you could find the same or similar sounds in other CA based black metal artists like Bosse-de-nage or Atlas Moth.
I don't think I could pick a definite favorite between Deafheaven and Defeater, though.
Defeater came through with a really dark and depressing (final?) addition to their 'broken post-WWII family' story. I figure final in the series, as this one makes it a trilogy, and the mom's parts are explained through the other three characters' story arcs.
And Deafheaven just generally make shit that shouldn't work, yet somehow does. I figure they're just a band that either you like them or you don't think they're KVLT enough.
