Halp with Gear choices

[Denchi]

Well there are tons of "BIS GEAR" threads on Elitest Jerks, and SP, and tons of stuff, and they all seem to list different things as BIS.

So I'm a holy priest, and I've gotten my hands on 3 chests that are "BIS" Just looking for more opinions. Here's my armory atm,

The World of Warcraft Armory

I have plenty of gear combos. I can get 600+ haste, or 20%+ Crit, or 2400+SP.
Anyways, between these, which would wear? Assuming there're all gemmed the same, and have +10stats, etc.

Valorous Robe Of Faith
Valorous Robe of Faith - Item - World of Warcraft

The Sanctum's Flowing Vestments
The Sanctum's Flowing Vestments - Item - World of Warcraft

Blanketing Robes of Snow
Blanketing Robes of Snow - Item - World of Warcraft

halp plz. I'm personally partial to the Valorous Robes, but I'm also pretty new to this game (Started in September), so I'm learnin' too.

I like that Valorous Robe myself, but I'm a fan of stacking mana regen and letting my heals sort themselves out in the process

Not a priest tho >_>
