So far (with young children) my son's been easier. My daughter has plenty of attitude and opposes my requests a lot more often. She does things on her time and demands her independence. I think it's based on preference, though. I was not the easiest of daughters, and thus may be biased. My son is not too hyper/active, but I hear boys generally are. So, if one prefers a little "sass" instead of constant activity, one may prefer raising a son. When my children become teens, I fear they will both deal with tough issues. Girls run the risk of getting pregnant in addition to being steered the wrong way by peer pressure (becoming curious and/or experimental with drugs, sex, etc.). I would assume that one additional risk makes girls more difficult, but if my daughter resists all temptations as I hope she will, she could turn out to be the easier child to raise. Personality decides so much. An easily influenced teenage boy who gets into trouble could turn out to be more difficult to raise than any girl.
