I am also having hard time choosing DPS to play. Can anyone rank the DPS in the below category ?

1. Single Target DPS - Long Fight (Ex. Twin fight)

2. AOE DPS - Long Fight (Ex. WP Speed Run)

3. Single Target DPS Burst (Ex. DPS race - Twin's Conflag)

4. AOE DPS Burst (Ex. DPS race - Twin Phase 3's snakes, Turn 4 mobs)
