George Mason or UMBC(university of maryland-baitmore county)? which one is better in computer science?

I am majoring in Computer Science and I want to go to these two universities for my master 's degree. Both of them are close to Washington DC and seem to be on the same reputation level. It's just so hard for me to decide which one I should choose. Which one do you think is better, or, is more reputable and have more job opportunities? Thank you very much!
