Those are both beautiful bikes designed with women in mind and I'm sure she will be happy with either one. As others have mentioned, it is more a matter of fit and "feel" than raw specs in that price range - both will have excellent components and both are excellent brands. I just want to clarify one thing though - when you mentioned long road rides you meant long one-day rides, correct? Because neither of those models is designed for mounting racks or other devices to carry panniers for overnight trips, something many of us on this forum use our bikes for. Assuming the bike is for those long day rides, either one will be excellent - take her down and see which one she prefers.
