I suggest that former VIP's Kirra is number 1. Simply the best. On Punter Planet she rates highly notwithstanding her infrequent visits, more retirements than Melba, and management usually mis-spelling her as Keria and Kerria.
The other observation I have is that lots of independent and agency escorts enjoy their independence and are unwilling to work in parlours, for a variety of reasons. It is perhaps unreasonable to compare top of the line independent escorts who only accept multiple hour bookings for many dollars, or who closely screen potential clients, with parlour workers who have different terms and conditions
