Don't believe in ranking clinics tbh. There is good doctors, bad doctors, great doctors or awful ones.
For sake of discussion I would say my recommendation will be :
FUT: H&W , Hattingen , Diep, Konior , Rahal. I put 1st 3 above the rest btw.
FUE: Devroye,Asmed, Rahal, couto,lorenzo
Value for money (if you are relatively on tight budget) : Asmed & Hattingen. Obviously plenty of Turkish HT surgeon are cheaper, but not of much quality.
I don't follow many American surgeons tbh, so I am probably missing few names. Due to their prices.
India have some top FUE surgeons, but not really well tested with other ethnicity to put them among the elite.
I agree with your point but not your reasoning.
I've been introduced to Hattingen lately, and I am liking them more and more especially for diffused hair loss. I am planning for HT in next couple of years and right now they are 1 on my list. Seems like a no bs clinic who makes best use of the grafts they take. And it isn't a well known clinic for English speaking forums like this one.
That is why it is difficult to rank clinics. In the Arab world It is either local clinics or Turkey, no one knows anything about H&W etc. And it isn't even Asmed or Yaman or Cinik etc. They are other doctors who specialized in middle eastern work and spent ton of money of marketing in Egypt and gulf area. You will be cursed if you suggested any other name outside of the half dozen Turkish doctors there. Although tbf many of them have got some outstanding results, and I would say there are 2 very good doctors here in Egypt, although not comparable to the elite level. But they can get you decent results for 1$ per graft
Same goes everywhere, what is known in German speaking world is different to this of English/Spanish/Indian/Chinese/Arab etc. There is probably thousands of doctors who do this surgery and tough to compare. Lots of factors in patients and type of surgery too.
