The recommendation to views ratio is low because it's hard for people to make a recommendation as it's your list. I couldn't really comment because I wouldn't be comfortable traveling to Turkey etc. Your list strikes me as a little bit strange. One is an expensive Western clinic, the others are far cheaper Turkish clinics with differing levels of patient posted results, so I don't see a common theme here. How did you narrow it down to these three names?
My issue with Erdogan is that he quotes too many grafts, but in this case his estimate matches the others. Additionally, his work looks quite consistent with plenty of patient posted results and not much negative feedback. If I was limiting myself to Turkey and wanted to do a lot of grafts, I'd probably be comfortable with his team.
