The Bori did metal just fine. Personally though they were a bit too exhausting for long sessions, but they are really good all-rounders that suits all genres. ZMF cans are my favorite though for rock/metal since they warm/relaxing and everything just sounded right. Aeolus are my personal favorite since they sounded great on both of my amps (Valhalla 2 and Jotunheim 2), and Auteur sounded amazing on my Valhalla 2 but too wide on my Jotunheim 2, wide to the point of being distracting.
So honestly, if you wanna save a few hundred bucks, go with the Bori. If you can spend the extra and want looks as well as great sound, you can't go wrong with Aeolus. If you plan on getting/have a tube amp and can spend a bit extra, Auteur. There's really no right answer to this though since they're all great headphones and it becomes subjective at this point.
EDIT: Just saw your follow up post. It's a shame you didn't like the ZMF ones, but I can understand them being too laid back for some. I personally see it as a plus since I like to relax with my music. I would recommend the Borealis if you're wanting more exciting cans if those are still on your radar. As far as Audeze, I've only used the GX and can say they sound good with metal with no EQ, but great with metal after a boost in the upper mids. GX is the one widely regarded as having the best tuning of Audeze, so take this as you will.
Yeah I'm torn between the GX, the 2F and the X right now. I can only demo the X :/
