BiS Gear changes in 5.1?

Hey, I was just wondering if any of our bis items have changed now that valor point upgrades are in the game? Would also appreciate it if someone could tell me which neck is actually bis currently, the Vizier one(haste+mastery) or the Blade lord one(crit+less mastery than the vizier one)?

To be determined, item upgrade mechanics are still being implemented into most theorycrafting tools because Blizzard did a very poor job of conveying the exact details of how the upgrade system worked.

Crit/Mastery neck is better than the Haste/Mastery neck because the gap between Haste and Crit is much larger than the gap between Crit and Mastery.
