Picking solely from OP's list I would have to go with Flora. I like her body proportions a lot, she creates a relaxing atmosphere, and while none of her individual skills are top-notch she does everything with enthusiasm and professionalism. Her waist chain just seals the deal adding a unique charm. She's also a good communicator.
That said, I think the list is missing some of the best in the gfe amp scene like Jojo (PH), Lucia (PH), Lucy (AL), Stacy (AD), and Bella (NYAW)
