Which is best? MISB Bocconi, SOIL India, Woxsen or Great Lakes chennai?

The best college depends on an individual's preferences and their future prospects. My friend is an alumnus of MISB Bocconi and was all praise of the institute's holistic approach. Listing a few perks he told me about the semester spent in Italy that gave him exposure at another level. The institute has a diverse faculty pool with professors from every corner of the world and top B Schools like IIMs. The student crowd is also heterogeneous and enhances the learning experience. All this helps you determine your inclinations and passions. 

I am not saying MISB is better than the other mentioned institutes. All I am saying is that every college caters to different kinds of students and you should look for the one that caters to your needs its better to talk to the current batch as well as the alumni to get a better understanding and then make an informed decision.
