Banishment vs Dust to Dust -- which do you prefer?

Which spell do you find better against larger quantities of yucky undead: Banishment or Dust to Dust?

Let's say you have a unit which can cast both (MotD, Caelum Hero, etc.), and you are facing lots of lower-quality undead (not equipped SCs).

Banishment: Larger area, no fatigue, but smaller damage, can be MR-negated.
Dust to Dust: Small area, 20 fatigue, more damage, cannot be negated.

Which do you like, and why?

ermorian longdeads have 9-10 mr .
banishment has 7+ an damage but mr negates .
normally ermor takes magic 3 for research so again -1 mr .

so banisment is optimal against ermorian fodder .
since the ai mostly uses this fodder against ai it is perfect.

as magnate said against scs you should take dust to dust or better wither bones .

other really good antiundead spells are blade wind and magma eruption . these are optimal for pangenea .


dust to dust is all in all not really good because it has 0 precision and area of effect only 1 .
so when you have nature / air mages with death pick it is good because you can cast aim / eagle eye but otherwise hitting is not so easy .
