decision help!

Hi! I have just been accepted to NC State and UNC Chapel Hill. I think these are both wonderful schools but I am having trouble with deciding. I'm not sure what I am going to major in but something to do with either biology or law. But either way I am planning on going to graduate school. I am asking for help if anyone has any advice on which school. I already have my Associate degree so I only have about two years til I go to graduate. I would like to go to NC state but I am asking if anyone knows, will I loose out on opportunities if I go there instead of Chapel Hill? (I am asking because that's what everyone is telling me but not sure if it's true). I would love to go to Chapel for my graduate but I want a diversity in colleges so wanted to get under grad somewhere different. But, I don't want to lose out on opportunities if I choose one school over the other. If anyone has any advice I would appreciate it. (sorry if this sounds confusing just didn't know how to word it).
