I think H&W have made their name doing great megasessions, not to say they can't do great work for lower norwoods, but megasessions is their "niche". Surgeons like Konior and Gabel are known for apart from refined hairlines they are known for really neat work when it comes to donor area scars. Cooley apart from being a well respected FUT surgeon is also very knowledgeable about dermatology and is an innovator.
The Indian clinics, I find them to be below the top Western ones when it comes to aesthetic appeal. They can move hair for sure, but artistically, they have some way to go, but may improve here on out.
Turkish clinics to look at: Demirsoy, Keser, Ozgur, Karadeniz.
