Subarus, Mitsubishis, Hondas, Toyotas and most of the turbo cars come with the wastegate valve closed under no boost and the valve only opens on the preset boost limit so one can say that theses cars are running 90% of the time with the wastegate valve closed. When they increase the boost on these cars all they do is keep the valve close for longer or closed all the time (when running 20 or more psi of boost
Are the turbos from bmw of inferior quality than all the turbo cars since the 70’s that came from factory with the wastegate closed?

It doesn't look like you are aware, on the N54 turbos build boost when Wastegate is closed opposite to other vehicles.
When it's not under boost, wastegates are open. If you force the turbos to be always on boost, by keeping the wastegates closed at all times, its a surefire way to blow your turbos quickly. I've been running 20psi for some time on a custom map, obviously trying to run 20psi all the time would have blown the turbos asap.
