Hey,
Definitely not an expert, so don’t quote me
-
Honestly they’re gonna be pretty equal, both top notch difficulty
-
Advantage UPenn IMO. Located in a major city
-
Again, they’re pretty even
Duke and UPenn (non-Wharton) are really close in terms on rankings, so at this point I would decide based on financial situation and “fit” (weather, campus vibes, etc)
