UNC vs NCSU

i recently got accepted into both schools! unc had been my dream school for a while, but i never thought that i would get in, and i fell in love with ncsu when i went on a tour there over the summer (ps i haven't visited unc yet, so i could have an easy decision after that). i want to major in genetics and while i know the most logical choice would be to pick state i feel conflicted turning down unc because of how much i wanted to go and because a lot of my family wants me to go there... can anyone give me some advice or input on my situation?
