See both the colleges have their own pros and cons, advantages and disadvantages, and their own uniqueness. But if I were you, then as per my personal choice I would've chosen NMIMS MUMBAI since it has got some amazing placements along with a great infrastructure and an active participation in many of the extra curricular activities. It's also known for its teaching faculty and educational facilities. Also as per the ranks, NMIMS is way ahead than PDPU university.
