Hello Sir. IITs are placed on a high pedestal than the NITs. If you have a long term plan of leading the world around you then IITs are best places to be in. Every top university of the world knows what IITs are and what IITians can do. A good academic record with few good recommendations can show you worlds top universities, which is not so easy with any other institute in India. IITs have a definite edge for higher studies or MBA in world’s leading institutes. IITs also have a better funding than the NITs. NITs are a little better than the new IITs but the brand of being an IITian is much more better.
