The answer changes depending on the content you're doing.
For MC/Ony content, rogues. You can bring 6-8 and they're all top damage. But you don't really have to seek after them because there's so fucking many, so I suppose the real answer is warlock/mage.
For AQ40+, fury warriors take over in maximum dps, but you can really only have 1-3 in your raids, and rogues get squeezed out a bit. Warlocks start to pick up speed here as 16 debuff slots enable shadow priest debuff and sm/ruin spec.
For naxx, it's all about the warlock. An optimal naxx raid would have 8 warlocks and maybe 6 mages.
