Indeed NSIT Delhi was the best engineering college in India but ever since it changed to NSUT, it has lost its charm and can no more be called the best engineering college.
However, NSUT has its own pros that people haven't been able to recognize as of yet. The infrastructure and hostel facilities have been improved and the TnP cell works harder than usual to ensure every student is placed. The college has not become autonomous so the administration is operated better. The introduction of new and diverse courses has started attracting a more diverse crowd thereby enhancing the overall learning experience.
All these combined have made both NSIT and NSUT a decent engineering college!
