moving the frames is helpful sometimes. it can give more room for brood and get them draw out faster. switching boxes, in my opinion is very rarely called for. if the queen has a preference for the top box, so what? the idea is to give her plenty of room to lay. where she does that should not matter. switching boxes is quite disruptive and rarely accomplishes what is intended.
that said, there are times when switching is worth a try. i have done it when i have found a lower super ignored while the upper is honey bound. in that case, switching the supers and redistributing the frames was helpful. the idea was to open the center, rather than force the queen up or down.
