Im at emory right now, and i think a big portion has to do whether you are comfortable where you are at. nebraska offers you d1 sports, especially football, no matter how crappy they were this season. I had a decision between Oklahoma, Emory, and Vandy, and i chose emory. i will say many times i do regret coming because lack of sports, but more importantly because im away from girlfriend, but educationally i dont regret coming. Its demanding, but its doable. a school like emory, washU, rice, etc are in cities where there is more opportunity, instead of lincoln. Im pretty sure there are going to be more research or medically-related opportunities on those campuses than neb. has (but i could be wrong) i will say that when talking to people, and saying that i go to emory, they look at me with more respect or they are impressed (now im not saying that wont do that for nebraska, but its a top 20 school vs. avg state school). i think educationally top 20 school will be more demanding, because you are competing with some very bright students from aroudn the country (i know neb has bright students too), but generally students at top 20 are more dedicated to studies, etc. remember though, i do regret not being in norman, oklahoma on a saturday afternoon in fall, and im sure you you will probably love lincoln on a saturday in fall. good luck, and congrats!
