This will depend on the role. We know for a fact that men are stronger than women physically. That's nature and that's the reality. However, there are some instances that women are better, like maturity, and kindness. They can bear our children too, so they have a huge role in mankind. What I'm saying is that men and women have different roles, and just like in experiments, you can never compare two variables that do different things. Imagine comparing a plumber to a carpenter.
