There will always be debate over the techniques, either patient to patient or clinic to clinic. They both have pros and cons and it is a hard question to really give defining answers to, so maybe better settle on a simple get out, it depends on what you need and what your donor can afford, of course with long term planning always in mind; so assuming both are performed to a high standard.
FUE is obviously more welcome for smaller procedures if only because it will not leave a linear scar so still allows the person to keep their hair shorter than strip could and even shaved. FUE becomes harder to advise the larger the session, either because of potential limits to harvesting so many grafts individually in one session or the impact it may have on the safe donor area again removing so many individual FU from a surface area that does not change and still leave the donor looking natural and not thin. That said I know I am the exception to the rule with FUE, but I did have a start donor density much higher than average.
Strip is obviously great for larger sessions and high NW cases when maybe FUE cannot safely reach the numbers in one session or even multiple sessions, and Strip can give the person much greater coverage quicker. OK, it leaves a linear scar but then no one said HT is all good and there will never be any visible signs of surgery, and most guys can accept this for the trade off of much more hair. Strip has the benefit over FUE that the area the hair is taken from is actually removed so the donor density is not as such effected, yes the laxity will alter slightly but not to the point more cannot be taken in the future. Because the area of extraction is concentrated generally more grafts can be taken in one session compared to FUE.
I opted for FUE, and was a NW5/6 when I started, luckily I had a really good donor and even so I am still relying on BH to finish my crown. I did this because I wanted to be able to shave still, something I couldn't have done if I went Strip. But if I didn't care about shaving I could have completed my restoration a few years ago, with less ops, one big Strip to start with probably giving me the same as 3 FUE sessions did. My point being it is all about what you have in your donor, what your goals and intentions are and the future, both are good techniques and used well and can combine well also.
