better product yields (you avoid saponification and problems in the
cleaning)
This means that in a production cycle it may be less expensive.

KOH is more expensive so people tend to go cheaper. I think both are
exothermic.

KOH dissolves much more readily, exothermically in fact. If you assume
that the NaOH and KOH you are using are 100% each (which they are not)
the ratio of KOH to NaOH varies by their formula weight KOH is 56 that
of NaOH is 40 therefore you would use 56/40 times as much KOH by weight.
