At what? Best for Defense is probably Dorm or Magik since they do guaranteed dmg with Mordo, Jugg, and UC (and maybe Hood) all being a pain in their own special ways. Mephisto is too but not many have him.
Best for power control is Magik with DV also being very good. SW can be but it's too random.
Hardest hitter I think is SW with her buffed s2.
Regen for AQ? Doctor Voodoo, GR, or Guillotine. Morningstar with all souls gathered is a beast also. DS is also possible but not great since nerf.
Nullifying - DS is best if duped. SW also great
Stun Lock - Loki and Thor JF can do this
All around - I'd say DV if it's not going to be a very long fight. SW or GR for the harder content. Magik is my favorite for war.
