I have done some research on Ferreira. He and Pinto are from the same place in Portugal and they are friends. Ferreira is also an exceptional dr. Maybe a little bit less conservative than Pinto. There are more cases out there on different forums with Pinto, but that is probably because Ferreira did not open his own clinic before 2017 (I think 2017). All the Ferreira I have seen seems excellent.
Bisanga is also a top dr, but I did not consider him as an option, so have not done too much research.
It is important that in the end you have to do your own research. Find all the cases of Pinto, Ferreira, Pekiner and compare them. (Are many different forums out there, not only this one) All of the surgeons have their own "signature" and style. Find out which one you prefer.
BTW: Pekiner is really hard to book. If you got an appointment now, then you are lucky.
