Both institutes are well-reputed and suitable for higher studies. But it is not possible to compare Harvard with JNU, as they both follow completely different structures and curricula. Harvard University stands out in terms of good academics, infrastructure, faculties, placement, and ranking.
JNU has a pulsating student culture, as they have various clubs and student-led organizations that result in the active participation of students in cultural and political activities. The students became socially oriented, and they should have a significant commitment to our society.
Both of them are unique and renowned.
