My D was accepted to both UCLA and Cal Poly, and putting aside the prestige factor and considering the importance of community and prioritizing her social/emotional well being, I am encouraging my daughter to accept Cal Poly over UCLA (though ultimately she will make the choice) from what I have read and heard from parents whose kids go to both, Cal Poly is a very collaborative environment, while UCLA is more competitive. Graduates from both tend to be in demand, so unless your kid works best under pressure and thrives on competition, your kid is would likely be better off at Cal Poly.
