This is a really dope discussion. Great insight too by both Uniquelyme and

These are just my personal views based off what I've experience myself first hand, solely exclusive to me. (Keep in mind I'm a black dude)
Providing & Dating-wise both:
Chinese women - I agree, some of the most professional, and pretty good service-wise. I've also come to notice they are extremely candid and direct too (which I appreciate honestly). They'll tell you straight up what they think. "You're ugly, you're handsome, you're fat, you have a good body, you're stupid, you're smart, etc." They pull no punches good or bad lol, and I think that's just Chinese women in general, whether in hobbying, AMPs, dating or otherwise. But yes service-wise I've noticed they can get very sloppy and nasty with the oral, some of the prominent DT'ers in the area currently happen to be Chinese and so on. I appreciate them. But admittedly, they aren't my favorite in terms hobbying or dating casually.
Japanese women - I agree service-wise they sometimes need to be directed and wait for you to take the lead. But sometimes they'll be a bit aggressive too, especially if you're "different" if you will. (You know what I mean by that, a dude of color, black or hispanic for example). They get to enact any sort of innate fantasies and desires they've had with you during the session, even if you're obviously there for your own pleasure. In my experience too even on the dating/civilian side they'll usually highlight and harp on your ethnic background and the usual stereotypes follow. Admittedly sometimes it's cool and makes you feel proud, but often times it's like (Damn do you do this with the white guys you provide for/date or any Asian gentlemen? lol) But it is what it is. This really isn't exclusive solely to Japanese women honestly, all 3 nations of women have done this with me, it's just I've noticed that Japanese ladies do it the most. Again, just my own personal experience. Service-wise though quite unique and seem more open to certain things and services (I obviously won't name here since this is public but you catch my drift) and more open to please in general.
Korean women - I'm shocking myself here with this one, but (to me) they're the holy grail of the 3, which is amazing to say as I thought Japanese women would be. But there are just certain things I prefer when it comes to Korean women over the other 2. I might be personally biased here since I have dated mostly Korean women lately in my civilian life, so maybe grain of salt perhaps lol. Korean women to me are diva-esque I concur, but it is well warranted I can't even be mad. They take such good care of themselves for the most part (as do Japanese women) physically, hygiene-wise, apparel-wise etc. Even the women on IG I mutually follow who are so into fitness, modeling and the like. They're just sexy to me. Service-wise is such a mixed bag with them. They can get filthy and nasty as you want but can also be so divinely passionate at the same time. And the amount of exposure I have with Korean women in general has me place them pretty high on my preference list. Be it Korean providers, Korean women I've dated or hooked up with, and even mere friends (who are still attractive), I'm really exposed to them more. Plus too, I can just relate to them more on a personal level in general anyway since out of the 3 they are the most versed when it comes to a lot of black or urban-culture too.
Anywho, if I had to pick I'd say Korean vs. Japanese is the "final bout" if you will, with the slight edge to Korean women. But if a gorgeous Chinese woman wanted to get with me, get married, have kids etc. I'm not going to be stupid and say no to her lol. I have love for all 3. Just my take!
