DW is much better for dungeons, scenarios, and challenge modes due to its superior AE.
DW is ~1.5% below 2H on single target DPS, but lots of raid encounters have adds/cleave/AE components, so in reality it's a toss-up between the two. Lots of people will see that 1.5% and go 2H, and there's less competition for 2H strength weapons as well. SMF beats titan's grip, so you really only compete with ret paladins.
