Probably a cultural differences thing (since I'm asian), but I find Milfy City (and many other western-made H-games) to be very superficial, like everything is a parody of real life.
Female characters are rarely depicted as modest person that are conscious about what they wear and it seems they want to seduced the MC from the get go, plus most of the times, they are either suspiciously super friendly or they are totally annoying bitches.
What's good about western game is how they established H-scenario.
And currently many of the new ones employed somekind of emotion simulation SLG elements (inhibition, horniness, etc) which makes interaction less predictable and pursuing characters is more organic (instead of just being a railroaded story-driven thing).
It makes you think how will the character react if you conquer them via romantic route vs coercion vs seduction.
