I have had a lot of BBKs from WW, Brembo, AP, and many more. AP's are damn nice indeed but "lessor" brands can do the job when properly setup and used. No issues at all with 18k miles on my WW DIY 11.75 front, 11" rear, 6 and 4 piston setups I designed and put together to fit under 15" wheels, track and street use, hot and cold weather. I am very hard on brakes on track but also know how to take care of cooling, pad selection and all the rest that goes into making them work and last.
I love AP brakes absolutely but I had to make due with what I could make fit my needs, WW does the job perfectly fine.
Any brake brand can be used improperly from those that put the system together to those that put them on the car, drive them, maintain them.....
I have had problems with most brands caused by driving beyond what they can deal with so had to upgrade them as things progressed, learning curve as my cars are never built like others and seldom can I find off the self solutions so have to work it out as I learned from experience in each situation.

Consider this:
Brake disk diameter, piston size, pad coverage, air flow, cooling, tire width and grip, driver style and more....big issue, how heavy are the wheels and tires and exactly how far out from center is the mass located, all that has a huge impact on brake effectiveness, heat induced and bled off, putting a large diameter rotor under taller wheels is not always the best answer, extreme example, look at F1 wheels and brakes
