Lets restate this philosophical problem as a problem of ontology

Imagine that you want to write a computer program that perfectly simulates what’s going on at the quantum level
Now the problem comes down to asking how many classes you need to define in your domain model

When you run your program will there be only one class of object instantiated (the wave class) or are there two different types of objects (of wave class and particle class) ?

The many worlds interpretation is equivalent to saying you only need to define one class in your model (wave class) because wave objects are all there are

Other interpretations are equivalent to saying you need to define at least two different classes (waves and particles) since both types of object can be instantiated and you also therefore need to define the interface showing the message passing between the two different types of object as per the rules of object oriented programming

When restating the problem in this way much confusion immediately clears

It should be obvious that the many worlds interpretation has much greater simplicity and clarity and that all other interpretations are in fact a return of dualism in disguise (with all the associated problem thereof). It is for that reason that many worlds wins hands down.
