Buy ready-made or build it yourself....
I think it also depends a lot on what you want. If the finished vehicle has everything you want, why not?
But if you have the space, you enjoy working on the car and you really want to have what you want on the car on the spot, then do it yourself.
In addition, the quality of the mechanics and the installed parts on the other side of the pond ranges from absolutely poor to top. In other words, a lot of crap can be installed that simply doesn't belong to the vehicle.
In addition, since Toyota was on the US market with the large Land Cruiser up to the 300, there is less in the way of building it yourself and therefore a comparatively incredibly wide range of accessories is simply available.
I had to wait about half a year for my roof rack from ARB because here in Germany, for example, only ~50 200s drive and I will build Rockslider myself this winter because there is nothing in Europe (well I don't really want one but my girlfriend is only 5ft tall so steps are an advantage

).
Personally, I like to work on the car, so I would go for the unmodified 200
