Definite girl. And tho left-right is difficult, I have an uncanny sense of direction. It's a visualization thing.
Women and men do generally seem to have different abilities with left-right and direction. Women seem prone to have difficulties in remembering their left from right. When I met my wife, she'd right left and right on the top of her sneakers to help her remember. She's terrible at navigation, unless she's inside a building - then she excels while I'm totally lost and rely on her to lead the way.
