They are all great professionals, and know how to service, including the more psychological aspects. You can get good service from others for cheaper, but these three somehow add in more of the psychological aspects, at least that’s been my experience.
IMO, these three are a cut above in looks and attractiveness (which also factors into the psychological aspects). If you place a high value on looks, then it may be worth the higher price point. After these three, I feel a high for a few days, bs a few hours for average amp girls.
As among the three, it’s probably personal preference as to looks and style. They all have had work done. If you like super full lips and ass, then probably Gisela. That’s not my thing, so I prefer Aurora and Koreanna. Personally, I think Koreanna has the hottest face; Aurora the hottest body.
I would put Bin up there too; but I think she is a few years older than the others. I’m older, so this is negligible for me, but if you are young and sensitive to the slightest tells of aging, you may notice (which may explain the price difference)
