Congrats on the CPI fellowship! I really wanted to apply for that but just couldn't schedule the GRE prep in time. I'm jealous! I would definitely go with that one. Journalism school isn't a necessity, a full ride is ideal, and doing the fellowship will make you stand out more than a degree from Columbia or NYU, in my opinion. I'm actually already in the field and was eying that fellowship with interest. I got into Columbia but might not even go. My personal order of preference would be Berkeley first (such a good investigative program, travel grants, and opportunities to work on Frontline), CPI fellowship second, and Columbia's Stabile program third. Unfortunately Berkeley turned me down. I don't know anything about NYU's program, unfortunately.
