It ultimately comes down to where you want to practice. Even if you get off the waitlist at KU, it does not appear that they place very well in Nebraksa. If you want to practice in Kansas, I think KU is obviously your first choice. I would caution taking on too much debt, but if you want to ultimately practice in Nebraska, Nebraska would be your better choice.
Nebraska may be your best bet anyway because you stated that you do not want to live in Topeka, and you do not want to be stuck living in a place you detest, especially during law school.
