From what I've read, there are two ways to approach gearing up a tank and that is to either stack stamina so as to survive bigger hits or to stack mitigation so you don't get hit as often and take less damage when you do. Both ways have their advantages and disadvantages and there are fights that favor one build over the other at times.
to elaborate further -
stack armor and stamina for progression; this gives your healers a more predictable rate of health loss to heal, and also more time to do it in.
stack avoidance and TPS (expertise/hit/SBV) for farming runs; your healers and dps already know what's up, so there are no surprises and you want to pump out the most threat and take the least amount of damage as possible so the raid can get to the goodies faster.
