Hi, MIT Manipal. It is among the top private Engineering colleges in the country, boasting of a better placement record than most other private institutes including NMIMS. The culture is immensely diverse and this is probably the coolest place to spend the 4 years of your college life. The infrastructure is pretty good as well. It also depends on what you wish to take up. MIT  Manipal is very well known for its engineering related core branches where as NMIMS MPSTME is well known for MBA courses. Both are equally good. If I had to choose one it would be MIT Manipal for Engineering. Hope this helps.
