I've only seen Coco and Happy personally. Angel and Pink are there too. I like Coco because of her skills, looks (in my opinion), overall personality, and her taking a liking to me. Happy is really cool too. She has skills, some looks, and a good demeanor. Coco not much of a rimmer but Happy loves rimming. Happy is on the larger side. Both really good providers. Never had Pink or Angel so no experience with them. Overall I would have to say personality and connection trump everything else. Nothing turns me on more than knowing they are being turned on and enjoying the experience just as much. That's just me though. Some prefer looks, others prefer skills, but we all prefer a positive attitude. That's my 2 cents.
