Hi Vidhan Saxena,

                            I am here to answer your query. Based on the few sources, Considering overall factors IHM Guwahati is better than Bhopal. I am answering this based on the OUTLOOK MAGAZINE review. According to it, IHM Guwahati is among the top 20 IHM's in Indian 2018 based on various factors like selection process, Academic excellence, Personality development, Infrastructure, Placements, etc. But What I suggest is you better try yourself learning more about these two IHM's and based on various factors and your priorities and comfort choose one of them.

 I hope this helps.

 Thank you.
