Generally accepted that WAR does more DPS than PLD. FFlogs does tell you how much DPS both tanks can push, but you need to account of DPS catering, bloating with more buffs (2 NIN, 2 MCH comp with AST buffs on 1 person is normally going to net a lot more DPS, coupled by having to not tank for the most part which allows the tank to just DPS). Not too mention that all of the top scorers are BiS or at least really close to it.

TLDR: WAR > DRK > PLD in DPS ranking in DPS stance.
