Different purposes. Brad-point drills are great for minimizing tearout
in face grain. They're also easier to locate precisely due to the
center spur.
They can both be HSS, high carbon steel, carbide-tipped, or whatever
other material you want. They can be made wherever.
Lee Valley has very nice Made in USA twist drills in HSS. Their HSS
brad-points start out as these twist drills, then LV grinds a spur and
lips on them.

Brad point = wood.
Twist = Other than wood; however, bits for plastic are plastic
specific.

The cheap crap is most likely from China.
If you want Fuller, both brad and twist, Jamestown Distributors has
them.
