But there is an important difference - you can observe the other stuff in our universe and therefore know that we are not (exceptionally) special in our universe. Other universes are usually per definition completely outside of our reach, as hard to grab as a god or Russell's teapot.

I agree! As in my other comments here, as long as there isn't any scientific result, I also won't regard the products of the proponents of such "interpretations" better than you.

Well, they're not completely outside our reach. Interference between our worlds and nearby ones is very testable, and the reason the theory exists.

That makes it out of reach. You cannot falsify the many-worlds-interpretation simply with interference. All other interpretations make the very same predictions.
