Tufts vs WashU vs Georgetown?

My DD was accepted to Georgetown, Tufts and Wash U and is having a difficult time deciding. She is unsure of her major but leaning towards education and child development (unknown in what capacity). No sports.All the same cost. Friends are important to her, and from the outside she seems very social, but does have bouts of introversion. We have always lived in big cities, and we have family in all three cities. Which has the best student life environment? Which is most helpful in later employment? Insight, please!
