Legplates of the Innocent is more balanced for a Holy pally. But it could be hard to get. It is the same example of the chess event shield, that I had never dropped.
So, Justicar could be a viable option, including the fact that it has tons of stamina and intellect. And it could be easier to get, depending on the progress of you guild.
I´m considering getting this and using it when I need a higher HP/mana pool.
