This depends on many variables IMO but females tend to be less high strung and often are more laid back making them the better choice for a house dog. That's not to say males cant be great in the house too because I have had my fair share of good males that were in the house too but the girls have always been much easier to have in the home. I believe (and have seen it with every dog I've ever owned) females attach to the male of the house and males tend to attach to the female in the home. With Kids, females being typically less hyped all the time and more nurturing by nature , IMO, make the better choice when it comes to living in the home with children. This is a generalization of course and will very dog to dog.
