I purposely avoided picking up the crafted chest because the tier chest is BiS and has no chance to drop from Baradin Hold. It is easily the best option of the three imo.
However, the crafted chest is getting a buff, and if you're attached to it, you should probably pick up the gloves. There is only 1 glove boss drop for prot and that has shared stats with dps specs. The stats on the tier gloves are perfect for a prot warrior and are BiS as well.
Legs drop from Baradin Hold, Atramedes and Al'akir, so assuming you're in a fairly competent and consistent raiding group, you have lots of potential chances/ options in the leg slot.
