I would pick Paley. Guichet would be my second option.
Please don't put everybody in the same bag. Paley and Guichet are the best. Betz is experienced but not really good because of a bunch of bad cases and dishonest behaviour (salesman). Monegal isn't good technically because he is unexperienced and he is dishonest too. They aren't good options. Patients have told me.
Ok, of course you are entitled to your opinion. This is why people join online communities. I would be more cautious though going so far and using so strong words, calling doctors you never met dishonest and unexperienced for many reasons, some of which are:
1) There are currently patients that are getting treated by these doctors. They read the forum. They have many worries now and one of them should not be the uncertainty whether they made the right choice with a doctor
2) There are many patients here who reported outstanding results and superior care/service by these doctors and their staff, so, at the very least, your words sharply contradict the opinion of people who experienced these doctors first hand. Instead, If I were you, I would invite these patients that supposedly told you, to come here, tell their full story, and contribute to the LL community.
3) Doctors read the forums. Again, these are all professionals with outstanding reputation who achieved a lot in life. Betz for instance developed his own device. It would be deeply offending for these people to come here and see that rumors that they are technically incompetent and lack care are being spread out.
To conclude, you know really well that the most highly regarded doctors have bad cases, and some of the so called budget doctors like the ones in India, Russia, China and Dr. Mitkovic produce outstanding results. It is up to the individual body, psychology etc, not only to the doctor's abilities, which in most cases do not differ.
