There is not an agreed-upon doc that is best. There are several dozen clinics that are the real deal and basically trustworthy (read: not Bosley), and maybe a dozen clinics that are considered “the A-list.”
Each clinic has its own set of cheerleaders on the net, and some of them are officially paid advocates of that clinic. So keep in mind the source when deciding whose advice you trust.
FUE doesn’t create more donor hair. Nothing does yet. We’re still basically robbing Peter to pay Paul with even the best HTs.
FUE basically amounts to using a tiny hole-saw and taking out hair follicle grafts one at a time. You get a couple thousand little tiny dots for scarring instead of one huge line. FUE scarring is not invisible but it can generally be buzzed down very short before it shows.
The downside of FUE is that it thins out the donor area and it costs about double what conventional HTs cost. The final graft survival rate is not as good as a top notch strip HT. (Although even FUE’s reduced graft survival rate is probably still better than the Bosley hackjob you’re comparing it to.)
The upside of FUE is that you get your whole head to pick grafts from. That means you can possibly get hairs grafted INTO you line-scar in the back. The graft survival rate there is not good but it can help minimize the appearance of the scar. The other big advantage of FUE is that the doc can take thinner-shafted hairs from the back of the neck, and use them on the hairline for added realism. (The standard donor hairs are thicker shafted than natural hairline hairs, which is part of the reason it has traditionally been so difficult to make nice hairlines with HT work.)
A lot of guys in your position elect to just go to a top-notch clinic and have another big strip-type HT session(s) done. They figure that their head is already permanently scarred anyway, so why pay for FUE work when good strip work is still offering more reliable and cheaper results? And at the same time, the second surgery can excise the original scar and reclose it with a tricho method. This is the best-looking closure method we have for line scars, it helps at least some hairs to regrow in the scar tissue.
Some of the best strip-type HT clinics are doing “megasessions” these days, which basically amounts to creating a very long scar and doing a TON of grafts in a single session. The recovery is worse than with smaller strips & FUE work, but at least you get more progress for your session. In ideal situations a clinic like Hasson & Wong can potenially do 4000+ grafts in a single strip session.
You might elect to go for FUE work along with more strip work. Lots of HT veterans have gone this route. It seems to be the best way to get the maximum amount of lifetime donor grafts from your head. Total lifetime max grafts can range from 3-4000 all the way up to a few outlandish cases of 9000+ grafts. It depends on the person, the degree of MPB, and the characteristics of their hair, and the type(s) of surgery used to extract the grafts.
