My main was my warlock because I used to do both PVE and PVP. Slowly I switched to Hunter because crucible is where it's at!! To me though the Hunter is much more versatile when maneuvering a map. Also, two offensive supers that can bring in more kills, rather than having one offensive super that are much more situational. (Fist of Panic and Oh-Nova Bomb) Rez is both offensive and defensive but easy to get shot back down if your not aware of your surroundings.
