Gear upgrades

Did Azjol Nerub and UK with a level 73 Paladin tank who had 14k health and 17k armour. I armoried him later and he had some items from questing which look nice:

Tundra Pauldrons reward from The Nexus quest.
Expelling Gauntlets reward from Azjol-Nerub quest.
Boots of the Unbowed Protector reward from The Nexus quest.

Also Gauntlets of the Disturbed Giant reward from The Nexus quest.

Not tank items but lots of armour and stamina:
Vambraces of the Vengeance Bringer reward from UK quest.
Girdle of Forceful Annihilation reward from Dragonblight group quest.

So it seems the quest rewards from The Nexus are better for tanking than those from UK. I need to get into The Nexus with these 3 quests and get completing them.
