I wore a system for two years and then went down the strong drug route (oral minoxidil, dutasteride, etc.)
Despite that I looked good and had an instant perfect norwood 1 again from my early 20s, I still prefer the drug route on the balance.
A hair system is a huge deal and the question of "worth it" very much factors in, in contrast to the easy and "biological" path of taking pills and having singular procedures. Frankly I would go so far as to say that a hair system is only worth it if your job and overall existence relies heavily on your appearance (actor, presenter, salesman, etc.); whereas most likely you are just some fat ugly old family man. With a system you are effectively trading one problem (the ugliness of balding) for another humongous problem (the existential problem of having to affix and manage a fragile synthetic object against your natural body forever on a 24/6 basis).
Remember that even the best hair system will never truly blend to your mind's satisfaction to your native hair, considering how the sides and temples themselves thin and recede, hair has minute differences in shading and also goes grey, and that you can never have a realistic hairline. And I say this as someone who had a good "profile" for blending: good temples, black hair, young face, comb forward hairstyle.
