There is some dispute about these findings, but even those who dispute them would probably for the most part acknowledge that a high conflict home is not as good for kids as a low conflict home.
However, something that most people fail to factor in is that the divided loyalties between the household of the father and the mother, plus the logistical and emotional difficulties that constantly moving back and forth between these homes produces, is a problem all unto itself. Also something many parents don't consider is that eventually one or both parents are apt to remarry (especially the man) and then another person, the new spouse, comes into the picture -- one who may for instance find the ex very threatening, or treat your kids unfairly / badly, or expose them to habits / behaviors you disapprove of mightily.
For more on this, see the book Between Two Worlds. I'm not arguing for or against divorce, simply pointing out that it's frigging complicated, in ways most people don't realize.
