White damage is a vital part of threat prodution. And it is measured by DPS of the weapon. The more DPS - the more white damage - the more threat produced.
While that is true, that is not the only concern. As a main tank in a 5 man or raid, the vast majority of your rage is going to be generated from taking damage, not doing damage. Your weapon is important for the initial threat/rage/aggro generation, but once you've established the initial aggro, it's not nearly as important. Sure it will increase your TPS because you're doing more white damage and with devastate, but for a prot warrior, your shield is probably more important than your weapon. Shield Slam is your highest threat attack and scales with the block value of your shield.
I still use the quest reward from killing Durn in Nagrand on my warrior for tanking. It may be the best non-epic tanking weapon in the game. It's pretty low DPS, but it has great stats.
