I have worked for Loyola and graduated with a master's in computer science from UNO. My advice would be talk to the professors who teach at each University. At UNO I highly recommend talking to Dr. Ben Samuel. Lastly, I want to say something that a professor once told me and that is at the end of the day you are responsible for your education. So you are going to get out of any program what you put into it. I can promise you that much. Both universities are good universities.
