Boerboel puppies are a much different animal than some of the other working type dogs, as as mastiff type.
The differences between a DP puppy and a Boerboel puppy are most likely night and day.
I understand what you are saying, that for a Boerboel, this pup is from high caliber working Boerboels.
The boerboel puppy is much better fit for a beginner dog owner with a bunch of kids, than many other "working dog" types. The intensity and the duration of the drives that a boerboel puppy will have should be much more manageable than a dog of another type.
I have worked with a big handful of boerboels and have seen a few others, they are not what I think of when I think of high drive working dogs.
THat is just a personal thing, not meant to slight the Boerboel in any way. I like boerboels, a good boerboel is a formidable dog to have around for protection, and from what I here a good overall farm type dog.
