I do not have any specific information about Delaware but I am sure that unlike UCF, it is an established program. I do not think it makes a big difference whether you get a security studies degree or political science but if you are interested in getting a job in intelligence organization, I believe UCF is a better option. However, given the limited resources UCF has, if you want to find a job in academia, I would suggest you avoid UCF. A friend of mine who is currently a PhD student at UCF told me that their method courses are not that good and students are only offered 3 methodology classes (1 qual and 2 quant).
