I've tried a couple of different brands and had great luck with both of them. Truly I doubt it really matters which brand as long as they are kevlar belted.

But you know what? I'd strongly suggest that ANYONE on a bicycle should know how to quickly and confidently change out a tube and how to rapidly and skillfully examine the tire carcase for embedded wire and glass to ensure that they avoid a sudden re-occurance. ESPECIALLY if they are commuting all over town. Kevlar belted tires may well reduce the need for this but they certainly do not eliminate it. Some training to bring your daughter up to a decent level of flat repair skill is definetly needed. There's no AAA autoclub for bicycles after all.
