Define your definition of "better". Better in what context? I doubt you'll come up with a good answer, because the argument is inherently subjective [and stupid]. Except when it comes to physical limitations, men and women have the capacity of doing the exact same things equally well. The "fact" that women, "are the ones caring for the children and the homes", doesn't support any argument that just because they do it, they are "better" at it than men. It's a gender role. While gender roles are important, they are not binding, and they don't mean a given gender is better at it than the other.
I could play your sexist game, I've played it plenty of times. But I'm going to shy away from the frivolous trenches this time. ;P
