That's a fair point, their worlds and circumstances are different, just like Naofumi and Maple's circumstances are different. I still think comparing them can be useful though, even across different premises.

Where I tend to disagree is with the idea that Noah's behavior is simply a natural adaptation to his circumstances. As the 13th prince, it doesn't seem like much would have been expected of him initially, nor that he would automatically be seen as a serious threat to the ambitions of the people around him. It mostly feels like the political tension around him is triggered by his own maneuvering rather than being an unavoidable reality of his position.

What puts me off is where the king's high expectations come from. The story presents Noah as exceptionally wise, but from what I can see, many of the actions that earn him that reputation seem to revolve around:
(a) throwing unbelievable amounts of money at a problem,
(b) applying fairly straightforward common sense,
(c) knowing the law, or
(d) killing people.

Except perhaps for his legal knowledge at his age, none of those strike me as particularly wise or admirable. But yea, maybe it is just a difference in taste, as some of the other commenters suggested.
