Stygy weapons in 3U were pretty much the equivalent of Jho weps in Tri, since they had more raw but less element. And Jho weapons got gutted in 3U anyways. So there's a few cases where Stygy weapons are superior, the SwagAxe being one. Also they have slots, which helped for set making.

It depends.
