I wouldn't presume to give one answer to this. To me, it comes down to a personal decision on what the individual wants. Some want to hang out in the back yard all day with a professionally-built stick burner while they feed it judiciously and adjust a vent here and there while drinking some beer. Not a thing wrong with that. Others want the experience of building their own cooker (whatever style) - learning new skills, finding special parts (this can be great fun) and showing off what it can do. Others want to prepare their food, put it in an easy to operate cooker and forget about it until it's done.
My decision was to buy a PBC. I like being able to hang my food, put the lid on and go to work. Or go fishing. Or run weekend errands. Or (my favorite) take a nap, all with knowing that I'm not going to screw it up due to inattention. And in the end I will have a finished product I am very happy with. I do dream of sitting under a shade tree next to a Shirley pit, tweaking a feast of smoked meat on it's way to perfection and staying cool with a frosty beverage. Hey, it's the American dream! But for my practical life, the PBC was the right choice for me.
