There is no one-size-fits-all answer to this question, as the best college for each student depends on the student's individual needs and preferences. However, we can provide some general information about NSIT and NIT to help you make a decision.
NSIT is ranked higher than NIT in several national and international college rankings, including the Times Higher Education World University Rankings, the Quacquarelli Symonds World University Rankings, and the Employment-Population Ratio. In addition, NSIT has a higher average starting salary for graduates than NIT.
However, NIT may be a better choice for some students due to its lower tuition fees, its location in a smaller city (which may be preferable for some students), and its slightly higher student-to-faculty ratio. Ultimately, the best decision for you will depend on your individual needs and preferences.
