4th job Single Target DPS

The Hero, because he doesn't have to recast SP?

Well, he needs to recast booster, AC and stance. Yet, I would say the hero would deal the most damage. He can spam brandish and deal with attacks which the night lord have to avoid/pot afterwards. The only times he have to pot, is when he is 1/1'd and when he is mp-drained. Aaand, he's able to survive without a party. Thus in theory, they are way "stronger".

All in all, the damage per second-threads are interesting, but saying class A owns class B at HT based by these threads is wrong.
