Yeah stinger is nice with a trillion stabs as well. Angels, I used Aquila's YY hold Y which brings all enemies to you then hold Y for the tornado. Angel weapons are more for crowd control than damage inducing weapons.
Also for your further runs take notice that there are many sections of enemies you can just run and avoid the fights for example mission 17. I'm currently sitting on mission 18 on Hell and Hell with just 2 hours and 39 minutes. They get shorter the more you play it
