You’re not likely to get a valid sample of informed opinions from CC posters familiar with all these programs at all 8 Ivies.
Suggestion: look up their graduate program rankings in these fields.
USNWR, the NRC, T.H.E., and others do department/program rankings … for whatever they’re worth (which may not be much, especially for undergrads). You may see more variation among professors within the same college as you do in overall program quality between any two Ivies that have the program you want.
