Honestly for the siren, you just can't go past the Combustion Hellfire SMG, pretty much solely for its increasing fire damage, its exploding rounds and (sometimes) high accuracy. If you manage to find a dark orange with with around 100+ dmg, with around 4-5 shots on any target, you can just leave them to die from the massive (15000+p/s) fire damage. Also, the "Saviour" class SMG's are good, due to their high magazines and ammo regen.
