Haste is easier to get that RNG Legendary gloves.
Also, Fury gear is the same to Prot gear and you can literally build both specs with the same gear apart from 1-2 trinkets basically, (Haste/Mastery).
In other words, if its not your main and you arent raiding with it in Mythic raiding a lot, you can simply go Fury and cover most aspects.
Arms = A bit higher ST dmg, useless without the legendary gloves, not fun.
Fury = Better in anything else, and has the same gearing as Prot, covering two specs.
