About identical particles, see my other comment at https://news.ycombinator.com/item?id=8556052 https://news.ycombinator.com/item?id=8556052 But the main point of why Bohmian mechanics over standard quantum mechanics is that the standard one is ill-defined. "Collapse happens when a measurement occurs, but not before." What is a measurement? Trying to make this precise is a problem. Collapse too early and you get the wrong results while collapse too late and you get into the cat paradox. Bohr, I believe, understood this which is why he advocated for a split between classical and quantum with a statement not to worry about the split. There are other ways of dealing with this problem, but Bohmian mechanics is the simplest in my opinion. Instead of something that is sometimes wave-like and sometimes particle-like, we have two things: a wave and a set of particles. The evolution of the particles is governed by the wave. Everything in standard quantum mechanics can be deduced by this picture.
