<p>I did UChicago undergrad, Stanford grad. Undergrads are comparably able at both institutions. The big difference concerns “look & feel” with Stanford more “academic superstore” and UChicago more “high-end boutique.” There is no meaningful difference, in aggregate, ranking-wise: in some places, Stanford leads, in others, UChicago rules the roost. Depends what you want to do.</p>
