N1K1 would see more use than the A6M2-N.
I bet the H8K2 would get decent use as well.
Well, when you put it like that.... lol I think of the three you list, the one that would most likely be added first would be the N1K1, for LW use. But the A6M2-N may be better, being able to cover a larger range in the timeline if I recall correctly.

Personally, I say add all three plus one, the H6K.
