Oy. Dangerous landscape here. Differences in talent or ability? Don't think so...differences in versatility? Perhaps. I have found the female voice to be able to "do more" than most male voices...more expressive, quicker and cleaner dynamic and tonal changes. Different, yes. Qualitatively better or worse.......nah. Better or worse instrumentalists...nope, again. The beauty is always in the ear of the beholder.
