It might also be worth noting that with their respective threat sustainables (Shield Oath/Defiance), The gap widens further in Warriors' favor.

Sword Oath adds an auto-attack for free. Compared to a Defiance-free Warrior, the skill is better obviously, yet Paladins still fall short. With Shield Oath, Paladins not only get the -20%, but they also lose that auto-attack, whereas with Defiance you merely lose damage but gain 10% Crit (which can be significant with Crit speccing and Internal Release) in addition to Unchained and Inner Beast. With the new 2.2 gear, the Crit cap for Warrior is something like ~620, which equates to about a 25% chance to crit. Couple that with Wrath's 10% and Internal Release's 10%, it comes to 45% which is certainly nothing to sneeze at. Let's also assume Vengeance will be used at some point, which is another (albeit small) DPS boost in Warrior's favor.

I can't give specific numbers, of course (parsing is against the rules) but, with these considered, you can safely say Warrior trumps Paladin in DPS, and absolutely murders them against multiple targets.
