Well, thats a very common thing to happen. People who had a surgery somewhere and either really liked it, or had complications but have some reason to blame themselves for it will really promote that surgeon because of the great work he has done on themselves in their subjective opinion. This is quite understandeable. Sadly sometimes it also happens with people not having great results because they are still happier than without those surgeries, especially SRS is such a topic where I sometimes get the impression that people are so happy to get rid of the parts they had before that it is secondary if the vulva created is not really that authentic or if the vagina is too short for heterosexual intercourse - especially if they happen to be lesbian, they may be happy with something I would never be happy with and still promote that surgeon (this mainly is from my experience with German Transwomen and german GRS surgeons who are in my opinion largely incompetent).
So I know it is an urge to promote ones surgeon. I would also always recommend Dr Kim for voice surgery over all others, because I think he did such great work on me and some others I know. But when choosing a surgeon, I now tend not to give much on people saying "I was there and it is great" but rather try to look at more objective things, like photos, numbers etc. But of course, a surgeon that everyone speaks of highly and more importantly that no one has any complaints about, is probably not a bad choice.
