I’m from the South (Atlanta, specifically).
For a straightforwards answer I tend to group Northwestern, Vanderbilt, Emory, and Georgetown together, with Cornell, Berkeley, Notre Dame, UCLA, Michigan, UNC together. If I had to rank them, I might go something like Northwestern, Georgetown, Vanderbilt, Emory, Cornell, UC-Berkeley, UCLA, Michigan, and UNC-Chapel Hill.
I have a tough time placing Notre Dame. On the one hand, I know it’s a good school; on the other hand, i feel like I mostly hear about it through football, and my mind is also colored by the fact that I am in academia and the other schools have good to excellent programs in my field and related fields while Notre Dame does not. I would definitely put it after UCLA, probably after Michigan, not sure if before or after UNC.
I’m talking mainly about my perception of undergraduate education at these schools in the here and now, and not alumni accomplishments.
And I know my Southernness weights heavily in my opinion, because I have a very high opinion of Vanderbilt and Emory. I went to high school when Emory was beginning to make the transition from excellent regional private to a more nationally known school, and when Vanderbilt was still one of the places that great Southern high school students went if they were wealthy or got a scholarship (along with Emory, Duke, and Tulane).
