I will focus on M&T because the other posters kind of ignored it lol. At the undergraduate level, those programs are will essentially give you the same education. UPenn will be a bit more practical than the others maybe, but the material will be largely the same. The advantage of UPenn M&T however is the very small number of students in the program and the amount of perks it receives on campus. You will essentially be on a pedestal. At the other schools, you’ll just be another student among thousands.
So (from what I know):
MIT = sheer technical rigor
Stanford = very solid all round + Silicon Valley startup edge
M&T = Wharton + pedestal on campus
Harvard = don’t know too much about harvard tbh but well it’s Harvard
