If you are planning to pursue research as a career, then no doubt these institutes are among the best in India. But in India, currently, earning money after B.Sc. and even M.Sc. is challenging as compared to MBBS. In the end, you should choose a degree of your choice because it is only then you would excel in your career. Also, both occupations are equally necessary; a country requires scientists and doctors to keep running the country, but unfortunately, only a few fractions of students take up research as compared to medicine.
