IMHO,
there is no best MP.
A Good MP must have at least a decent room, bathtub. No need to be damn new but adequate room decor enhances the session.
A Good Chia Keh. Another term for OKT. Getting one which is experienced, eager to service the customer is a top priority for every cheongster that goes to MP. With their contacts and feedback, you will get top horses from the stable and not forgetting some you see good in the showcase, doesn't mean good on the bed. The tip of course helps. Tipping of 100-500baht (depending on the tipper) often makes the Chia Keh remembers the customer.
A Girl that clicks. Sometimes when a man is faced with a girl that BBBJ, CIM, GF Treatment, doesn't mean he will click with the girl. Getting one with the X-factor, even condomed BJ, the man also nevermind.
With the above 3 major factors, any massage parlour can be anyone's favourite. Anytime, anywhere.
