<p>In deciding to which college I wanted to apply early, I asked myself the same question as you, the answer to which was a major factor in my decision. </p>
<p>Out of all the colleges you mentioned, Princeton is known to pay the most individual attention to the student (while Yale is close behind). Some people don't like the thought of "hand-holding": they like to imagine themselves in college as totally free and independent. While Princeton affords that independence to students, it is also known for keeping its students happy and paying special attention to the individual. First of all, of all the schools you mentioned, Princeton has the best student : professor ratio (see US news data), plus their classes are broken up into precepts which meet every week or so. That means that students get more individualized attention from professors than at YHS (and also, Princeton's star professors teach undergrads, whereas H's and S's stars more commonly teach at the grad schools, leaving the undergrads to the younger, inexperienced professors). Secondly, since Princeton is outside of NYC, as opposed to right inside of or next to a major city, the student body is very tight-knit, and students are among the happiest in the country (according to P. Review, which I should mention isn't affiliated with the school in any way), also having the highest alumni donation rate in the country by a very large margin. Also, since Princeton is the only of the schools you mentioned without a large grad school program, its reputation comes purely from its focus on you, the undergraduate, as opposed to the other schools' reputations based on their law/business/med schools. It also has the largest endowment per capita of any school in the world (most financial resources to spend on each student). As to which one will stroke your ego, honestly I'm not sure that any of the schools you mentioned will give you that feeling, since all are filled with the best and brightest. That doesn't mean, though, that you'll be forgotten. At Princeton, for instance, if you can't make it home for Thanksgiving, the school's president invites you to her house for Thanksgiving dinner. If you told dean Hargadon your name, legend had it that he'd remember what was special about your application. That's pretty warm and fuzzy, if you ask me! Even though you might be surrounded by geniuses, Princeton doesn't seem to lose sight of the individual. (Whereas I've heard that at H, the graduate schools are the highest priority while undergrads are neglected, and at S, the administration is not active in guiding the students toward successful futures and students are left on their own.)</p>
<p>One thing in particular that drew me to Pton was the fact that, of HYP, its students didn't seem to be cutthroat in the least. As you can see from these boards, in fact, they seem to be very spirited and enthusiastic in pursuing their own interests, rather than competing with or discrediting others. So, while it a highly intellectual environment, it is not a very threatening place to learn. Also, although it is known as the "preppiest" of the schools you mentioned, that image is far from the truth. Actually, Princeton has the highest percentage of kids on financial aid, and it offers the best financial aid program, which attracts a wide range of students. </p>
<p>Obviously this is a little one-sided, but my polarized opinions aren't because of my future-Princetonan status. On the contrary, my Princetonian status is a result of my opinions; based on what I found when looking into all of the schools you mentioned, I couldn't resist applying to Princeton early, and I'm very happy with that decision.</p>
