I can say for certain that it is easier for me to understand quantum than metaphysics . Both try to explain something we may not see is there, one uses scientific methods to arrive at hypothesis. The other uses superstition .

The significant difference is that one makes predictions with breathtaking accuracy about reality. The other makes stuff up, and when its predictions inevitably fail, just makes new stuff up and says, "That's what we meant all along."

The quantum case is that there's something there beyond our intuition but it's there to comprehend with better models, and it adds up to something being there.

The superstitious case is that our intuition believes something is there when there isn't and it provides no functional model whatsoever. There is nothing there.
