"My daughter wants a phone with a capacitive touch screen. They seem more expensive, what advantages do they offer over other types of touch screen?

There are three types of touch screen: capacitive, resistive and surface acoustive wave. Over the other two, the capacitive emits 90% of light ray, making the screen clearer compared to the other types of touch screen. The capacitive touch screens can only function with the use of fingers, meaning that a stylus would not be needed. The benefit of this is that she wouldn't be worrying about losing a stylus. Also, it has a long life because of its resistivity to things other than human skin.
