Fascinating thread over at the other site comparing SAT scores and college admissions between NYC's top public (magnet) school (Stuyvesant) and top private school (Horace Mann). Perhaps by chance a huge percentage of my friends from college also happened to attend those two high schools.
In my experience (small sample size warning), the Stuy kids were smarter... and nicer. But apparently, colleges like the HM kids more.
