<p>Excellent question.</p>
<p>I live with a guy from Princeton, so with some anecdotes from him, i'll try to give you both sides.</p>
<p>Columbia obviously offers both the pros and cons of being in a big city, whereas Princeton offers the pros and cons of being its own little bubble in (comparatively) the middle of nowhere. Some major differences:</p>
<ul>
<li><p>You have to worry about crime at Columbia: laptops get stolen, pockets get picked on the subways, bikes get taken, etc. Generally, unless you do something stupid you're fine, but it's a background stress. Dorms are more secure because of round-the-clock doormen. At Princeton, students will regularly leave their laptops lying around the student center to go get a cup of coffee, it's much more free and easy.</p></li>
<li><p>Things are open all night at Columbia. Pizza joints are open till 4 (Pinnacle is all night), 4 local supermarkets within 10 blocks are open all night, Tom's Diner (of Seinfeld fame) is open till 3:30AM as are the many bars in the area. At Princeton, they roll up the sidewalks substantially earlier and you have to drive to find anything open late.</p></li>
<li><p>Columbia's student body is much more diverse. There's a huge percentage of students who are international or URMs, whereas at Princeton it's much more homogeneous. My roommate was in the eating club that the black student union joined, and they basically circled the wagons and didn't say much to everyone else.</p></li>
<li><p>Living space at Columbia is a double-edged sword: people are put into dense corridor-style dorms or apartment-style suites. However, any freshman who wants a single can get one (unusual at most schools), and a few upperclass dorms have big living rooms and bedrooms. Space is more generous at Princeton, although a greater percentage of students have roommates.</p></li>
<li><p>Eating clubs form the nexus of social interaction (and parties) at Princeton. Selection can, on occasion, be catty or political - they're essentially frats. These things are big, unsupervised and well-funded (many have their own chef, which club dues pay for year-round). Columbia's frats often have parties too, if that's your thing, but many other students have parties in their rooms, floors, suites, or even off-campus. The frats are a nonessential part of social activity.</p></li>
<li><p>In both places, most people make a bunch of friends from people they meet in their classes and those who live near them freshman year. Students have social circles after the first few weeks but generally stay open-minded.</p></li>
<li><p>It's an hour-and-a-half train ride from Princeton to NYC, and that only gets you to the train station. The last 4 miles from the "Princeton Junction" train station to campus are run by a jitney bus that stops service around midnight. Aside from that, cabs can be very predatory, charging whatever they think they can get the silly rich kids to pay (my buddy got hosed for $20 for those 4 miles when he went to visit his girlfriend on saturday). Columbia is 10 minutes from the restaurants and bars of the upper west side, 20 minutes from most of midtown or the west village, and 45 minutes from brooklyn if you really feel like exploring.</p></li>
<li><p>Columbia's campus buildings can have a spectacular view, not just of the campus but of all of the manhattan skyline. If you're clever, you might learn how to go up on the roof of some of those buildings. Princeton's campus has a lot more trees and natural scenery (not that Columbia's is barren, but the % of concrete is sure higher), and a lot more space between buildings.</p></li>
</ul>
<p>One of the things that makes Columbia unique is that because we actually have a campus, with a quad, lawns, <em>gasp</em> trees, etc (as opposed to, say, NYU), there is actually life on campus. During nice weather, hundreds of students will sit out on the steps and hang out, play music, pretend to work, play football or frisbee on south lawn, etc. At night on the weekends, certainly many people go downtown, but there's also plenty to do that doesn't require a commute or subway fare (both of which are enough disincentives for some students), so many choose to hang out on campus. Obviously, with hundreds of student organizations, both schools have a bunch of activity options for those looking to do something other than party.</p>
<p>My recommendation is to try to stay overnight at both places - ideally on a weekend - before making a decision. IMHO that is the absolute best way to get a sense of a campus and its students and social life. If you ask me or my roommate, neither of us would have wanted to trade our experience for the other school, so obviously either one makes a lot of people happy.</p>
<p>Hope that helps,
