Well that's a very tough question to answer, when you're trying to choose between two cameras for somebody else. The reason being is that everyone has different wants and needs to the next person, so the things that might attract me to choose one particular model for myself, would put another person clean off the same camera.
I would always suggest that she tries both cameras herself to see which one she favours using. Performance wise, there's not that much to choose between them, so it will come down to the ergonomics, the controls and the layout of the menus of each camera. Let her way up the pros and cons of each and then pick a favourite. If she's allowed to choose the camera that she finds a real joy to use, chances are she will enjoy her photography more and not be constantly bugged by the question "I wonder whether the other camera would have been a better choice for me?" Of course, she doesn't like either of them then she'll have to try a few others within your budget to see which comes out tops.
Buying a camera is a very personal decision and not one you can let anyone else make for you! Best of luck!
