The haste buff, by far. If you're the only physical dps, (assuming the warrior is a tank) then the only people who benefit from the 4% phys damage or the 12% armor reduc are the tanks and yourself; meaning the raid gets far more benefit from 10% haste.
I don't think ranged haste applies to casters so it would only benefit you and the Hunters if you have any? Still it's probably better than the 4% physical.
With active mitigation from tanks now, melee haste buff is actually a buff to make them stay alive better, and now with how vengence works, tank dps i quite high as well so that gets increased as well.
And from your perspective alone, you get most benefit from the haste buff because a lot of SVs' damage is magical damage.
