The wave of villainess manga has now spawned a new wave of villainous noble manga and the market is becoming oversaturated. I personally like the villainess manga more since they focus more on the characters. But they have the same issue of the FMC being a Mary sue and that all of her ideas are perfect or if she just copies amazon, which copies sears and roebuck. But all of this in a medieval setting where everything was custom ordered and hand delivered anyway. Villainess manga present a female power fantasy of being born a high noble with no real responsibilities and then being always right in all aspects of life, and then going to Mary to Prince/king of the country. While a male fantasy mainly focuses on becoming super OP to the point that even kings of nations must bow down before him. And also collecting one or possibly more waifus.
I have to say though that my favorite mangas are where the mc romantic plot only focuses on a single well written female lead. Instead of a bunch of cardboard cutouts with a range of breast sizes
