What’s the other school, if you don’t mind me asking? This is my field, and knowing to which college you are comparing UCI could be helpful.
Irvine seems to have a lot of younger faculty which is an indication of growth and investment by the university, and means that there is likely a lot of energy in the department. This will translate to more interesting classes and more focus on contemporary issues. It will also likely mean that there will be more interest in having undergraduates in the labs.
It is a pretty good department overall with a good reputation. I am a bit out of the loop, since I have stepped away from academia, though.
What particular directions interest your daughter?
