In abstract, yes, in reality concerning EU4, stacking monarch point discounts is much stronger strategy than stacking military power, as it is very easy to get more military, and above certain point, you don`t need more military power.Ok. Simple example:
Brandenburg have superior military ideas (top tier ideas, if you want to be warmonger). So, you can choose your idea sets based on your NIs. You can grab administrative for better mercs and -25% coring cost. Or you can go full warmonger with ~100% army tradition.
As Muscovy you have good set of expansion ideas. So, you can go quality or improve your ideas with quantity+expansion.
Basically, you're choosing between improving your weaknesses or maximizing your strengths.
I`m perfectly fine with playing a state without military-related NIs and only picking 2 military ideas, Offencive+Aristocracy/Defencive/Quantity/Qality.
Muscowy`s ideas are better, because they allow stacking stronger bonuses, or going good at everything strategy.
Hell, I said it, teutonic ideas are better, because they are not as military-focused.
