Like you say, there is definitely something exciting about the sense of the unknown, and I do get a great buzz when I find a really nice girl.
On the other hand, if I have an experience that is not great, I will want to choose my next girl from those that have numerous good reviews.
So I think both positions are good, but I think that those of an established escort with a lot of good reviews is a better one on the basis that the popular established escorts can be very difficult to get a booking from, probably meaning that they are too busy.
The Gods are just, and of our pleasant vices
Make instruments to plague us
