All India Institute of Medical Sciences, Delhi

AIIMS Jodhpur is the best among these. It offers good infrastructure, faculty, and facilities. Faculty members are well-experienced and passionate about teaching. The labs are cutting-edge. Students get access to the latest technologies and devices for learning. AIIMS Jodhpur has better sports facilities compared to any of the new AIIMS. The campus has a good research culture. If you are interested in pursuing research, you will have decent opportunities. So when we compare all three in terms of location, Bhopal wins, but infrastructure and teaching facilities are better at the Jodhpur campus. AIIMS Patna campus is also good but not as good as these two. I hope this will help you.

Among these institutes AIIMS Bibi Nagar is the worst one as BB Nagar there very less number of patients which are all handled by doctors only in Osmania University is 80% of the patients are seen or concluded by the students and you have to do 80% or more than 80% of curriculum yourself no teacher or doctor will be involved until and unless good case comes now if we compare Gandhi institute and Osmania institute Gandhi institute is newly made so its infrastructure is quite good but Osmania institute is the oldest institute you can say so the infrastructure there is quite low the education in Osmania institute is very good as stated earlier and Gandhi institute is also good so you can and its infrastructure is also good so choose either Gandhi institute or osmania institute but Osmania institute will be a better choice.
