Apart from one amazing private lady that I saw regularly, I find establishment ladies tend to be more relaxed as they are working in their own place with supportive colleagues rather than a hotel room which maybe hers or the clients. Also an establishment lady doesn't have to worry about the admin side of it, or handling or counting the money and it's also easier for the client. Also as a client, organising a lady privately is always more stressful and I know this is the case for the lady too.
