Hey, I’m in the same boat as you. I’m deciding between Stanford and Princeton. Honestly, both schools are amazing, but I ended up choosing Stanford.
In terms of prestige, both schools are world-renowned. Regardless of major, you would be getting an amazing education. Though, Stanford is more known for its entrepreneur and research environment, while Princeton is known for its law and economics.
In terms of education, I would have to say Stanford hands-down. Princeton’s grade deflation was a HUGE turnoff (only a certain # of A’s allowed). I don’t care so much for not getting the A, but grade deflation creates unnecessary conflict and stress between students. I want to learn, not compete with students, so I choose Stanford. That is not to say that there won’t be conflict because at any school full of bright individuals, you will have some conflict. Since you are more laid back, Stanford would probably be a better fit. Stanford’s quarter system might be an issue due to the fast pacing, but considering you got into Stanford. You should be fine.
Location is a bit different for you and me. I’ve never been to California, so it would be a nice change of pace. Though I plan on going somewhere up North for graduate school. Since you live there, going up to Princeton might be better. When I went to visit schools up North, I was not prepared for the weather since I live in the South. However, with a little planning and shopping for winter clothes, you should be fine.
Another point that I really considered was social scene and environment. You would probably have a more enjoyable and active environment under the California sun, but my older brother, who goes to another Ivy, has never had a lack of enjoying the environment. Princeton is more connected and accessible to the rest of the world with the subway systems than Stanford, which from what I’ve read is limited to biking and cars.
If you still can’t decide, make sure to visit both schools, which is what I’m doing even though I am pretty set on Stanford. Better to be sure that you “fit” than regret it down the line.
