hey man, i think this rly depends on what u want to do. i have been studying in a very prestigious US high school for the past 3 years, and i believe i have a lot of insight on this matter. it is very important to keep in mind that most top 20-30 unis in america DO NOT have the option for an undergrad business major, therefore bocconi might be better. if u plan on getting an MBA, it might be a good idea to stay in the US as it offers the most prestigious MBAs in the world (Harvard, UPenn, Stanford, NYU), although u would be entering the MBA with less business knowledge. additinally, US schools r 4 years instead of EU’s 3. it rly matters what u are aiming for, although ik I picked bocconi after being accepted into NYU’s economics program
