Should I attend San Jose State University or Portland State University for Computer Science if I'll receive cheap tuition at both? Why?

Both of them are equally good and provide comparatively cheaper education in the field of Computer Science. The only difference you will experience is in the living conditions, location, cheaper lifestyle, etc. Some other things you should focus about are the placement opportunities, average salary obtained by the students of that University, living expenses, etc.
