Dear Sankalp,

Academics wise, in most of the colleges is almost same and you have to study on your own but the colleges you have listed above have the best faculties.

VMMC - You will get delhi quota for pg. Safdarjung hospital has the largest opd so you will get excellent clinical exposure, helpful seniors, good alumni connections, good pg:ug seat ratio(sort of internal pg quota), campus is not very big but college life is amazing. No service bond after MBBS.

KGMU - It caters large number of patients so good clinical exposure. It has a golden era of its own with great alumni. Two  Years of rural service bond.

AIIMS Bhopal -  You will get aiims tag in the first two, three of them are central universities with internal pg quota. I have ranked them according to my priority. You will also get good amount of research opportunities.

IMS - It is an Excellent institute but with a very disciplined life. Choose only if u want it, but it will be a good experience on its own.

Overall, Aiims bhopal is best. Initially BHU was better one as it was giving preference for internal students. But now, there is no such type of internal preferences. So now AIIMS will a better choice plus the brand tag of aiims also works everywhere . Facilities like mess, hostel etc. are gone quite old at BHU.

Hope this helps.

All the Best!!
