First off, "top 5" doesn't really tell you anything because there are several different authorities making "top _" lists all the time. Going to film school wont be about textbook learning....it will be about making connections and learning through experience, which is extremely difficult to do on your own. Ask any expert in the industry, the value of film school is 80% community, 20% academics. Again, none of this means you won't become what you want. You asked how it compares, and I told you based on what I know. Best of luck making a decision.
