Students are the representative of the universities. So the ground realities that are known to the students. As per the reviews available online, Jain University is btter than that of Christ University in terms of Faculties as well as well augmented teaching and curiculumn.

Depending upon this review only, you shouldn't take the decision. I would say if you can contact some students of both the university discuss with them if possible or investigate otherwise and then only you take decision. But depending on the online data available Jain University will be better.

I hope my answer helps. All the very best for your future endeavors!
