Epic quest class armor/weapons vs. "town/area" armor/weapons vs. Battleground bounty point weapons

Sperlock

When receiving epic quest class armor/weapons, town/area quest armor/weapons, and looking at Battleground weapons that are purchased with bounty points, what is your determining factor on which to use? Level (color) of the armor/weapon, armor factor, dps, stat/skill/resist buffs, etc.?
