I have a degree in physics, and I can tell you that there is no
*observable* difference between many-worlds and any other
interpretation. As far as I know, the only thing that we can observe a
difference between is local hidden variable theories and quantum
mechanics. Google: "Bell's inequality"

I would suggest that you stop reading popular books about physics and
move on to something like Sakurai.
Popular books tend to shroud things in nonsense because they aren't
allowed to use equations.
