Yep, I would agree and it seems to be a popular generalization about the two schools. People often cite a great deal of overlap in the student application pool as well. Nothing in my travels at each place suggests that those generalizations are not well founded. Of course, I’m not the one who attended, but listening to my kids talk and getting to know their friends, yeah, I’d say Brown and Wesleyan are very similar in terms of student body. I think there’s probably no safer Ivy to choose if one is convinced that Wes is a good fit. If you’re looking for a hair to split, then maybe, maybe, Wesleyan is a smidge more politically active, though this whole Gaza business has been no less intense at Brown than at Wesleyan. In fact, it might have been more blown up at Brown. Still, Wesleyan has that reputation, and it’s not entirely undeserved (though almost always exaggerated).
Of course, size and location presents some differences, but I really like both places. We all really like Providence a lot and score it as a place we could actually live (well, I score it that way). I also like many things about Middletown, but would probably never find myself randomly choosing it as a place to live. Brown has a really nice campus and, when combined with College Hill generally, presents a physical location that is exceptionally nice and to my liking. Again, Wesleyan is very nice IMHO but I’d probably give the nod to Brown on the overall variable of “place”, as I would over really any of the NESCACs.
Of course, Brown is an Ivy League school, which commands brand power like Porsche. Though I hasten to add that it has been my observation that the NESCAC brand, intentionally or not, has become a real thing. You hear kids 3,200 miles away from New England say, “do you think I could get into a NESCAC school?” or “good enough to play NESCAC?”. It has a ways to go before it catches up with the Ivy League, but it’s not nothing.
I know next to nothing about Brown’s gravitas in public policy and am aware of the things @circuitrider said in his post about Wes’. Neither of my kids have spent much time in that space, so I’ll not try and make a comparison there.
Wes is smaller, which I always think is a plus, but Brown is not exactly a state flagship. Still, you will experience Wesleyan (as you would any LAC) on a slightly more human scale, but Brown does not feel impersonal.
Small random anecdote: we were walking together on Brown’s campus one day, and we ran into another family whose kid was matriculating to Brown. With her was her sister, who was attending Wesleyan.
