<p>They're both great academic institutions, and their general prestige (outside the business area) is really pretty equivalent. Penn undergrad is twice the size of Brown -- more stimulation or less intimate, depending on how you look at it -- and the university as a whole is probably 3-4 times larger. Wharton (grad and undergrad) is a huge part of Penn; you are much more likely to run into businessy types there compared to Brown.</p>
<p>Brown feels intimate and set apart from the city (but close). Penn feels really urban, with lots of lovely nooks and crannies. Brown is doubtless "safer", but it's wrong to think of Penn as "unsafe" or Brown as "safe". It's really a question of Penn being much more integrated with a much larger city than Brown. The average dorm at Brown is probably nicer than the average dorm at Penn, but it's hard to characterize Penn because there's such variation. More kids will live off-campus at Penn. The area around Penn has gotten much nicer over the past 20 years; Penn's last president did a lot to improve it. </p>
<p>Philadelphia is a much larger city than Providence (although BOTH have rivers running through them and convenient airports). There is a lot more going on there culturally, business-wise, research-wise (outside the university itself), and a lot more students of various stripes (although Providence has plenty). For the frequent trip, New York is about the same distance from Philadelphia as Boston is from Providence.</p>
<p>Penn takes sports, especially football and basketball, much more seriously than Brown. People care, sometimes to the point of obnoxiousness. Philadelphia is probably the best college hoops town in the country (all of the major local teams play each other every year, and that, not the Ivy League, is really what Penn sees as its competition).</p>
<p>For my money, probably the biggest negative on Brown is that people always talk about going to the nice downtown mall. It is nice, for a mall, but it's fundamentally a mall. At Penn, people don't regard going to a mall as something to do unless you have to.</p>
<p>Really, you should relax, congratulate yourself on your great options, and go with your gut about the schools.</p>
