This topic is still a widely discussed one. There are pros and cons and no clear answer for now. I personally don't like it much for some of the usual reasons.

Moreover, there is an excellent agreement between all current experimental data and predictions made in the context of the Copenhagen interpretation. This is enough for me :)

Indeed this is still a debated topic. Since they are just interpretations, I am open minded to both of them :)

Well, when calculations are at stake, the easiest is the best :)
