I'd be a little cautious about IU if your daughter really has her heart set on being in a sorority. I know many will agree that they have one of the most (if not the) brutal recruitments in the country. My own sorority colonized there last year, and a large pnm pool competed for a very limited number of spots. It was probably no different for the sorority that just colonized this semester.
All of the schools the OP listed have great reputations and some have very competitive recruitments, but none as competitive as Indiana. Good luck
