slightly more famous name
There's often a bigger discrepancy between the "fame" of 2 schools than "slight." And the differences aren't always about prestige. I saw a university BRAG about a faculty student ratio of 1 to 19. There are top schools where it's more like 1 to 7. Class size might be dramatically different. One might have a great career center and another might not. It might be common at one college for it to take 5 years to graduate due to course restrictions while another might graduate 90%+ in 4 years.
