I have had both and felt that it was a wash.
The boy was harder when he was young, always pushing the limits and hard to discipline, but when he reached 12 suddenly he became sweet and cooperative. I think it was because he finally realized that females are desireable, not disgusting, and appearances to the contrary, Mom is female.
My girls, on the other hand, were a delight UNTIL they reached 12, and then they turned into horrible monsters that caused us every problem in the books. I wouldn't wish teenaged girls on my worst enemy! Even my calmest, most tractable DD became sullen and balky then.
However, the good news is that they DO grow out of it, and my 4 DDs are each a joy to me now in their own different ways.
