As with most aspects of medical school/residency, the claims are overstated. Neurosurgery is indeed demanding; however, programs vary with respect to lifestyle and demands. For instance, while there are still Q3 programs (most of which are changing to at least Q4) there are also programs whose call schedules are better than many non-surgical residencies (Q5-Q8). I would encourage a rotation at programs that are at both ends of the spectrum.
A valuable lesson I learned on the interview trail is that most claims about programs/residency programs are unfounded. Also, don't be fooled into thinking that NS is now an easier match. It is true that the % that match is up and that the number of applicants has gone down. But, many students have taken a shot-gun approach to the match and have applied to a record number of positions, unparalleled by previous years. Also, if you ask the residency program director at your institution about the quality of their applicants, they will more than likely tell you that they are as competitive and as impressive as ever.
