Umm it is a clash of titans, i must say both DTU and NIT have images of their own...you better compare the placement record of the two and also try to cull out information regarding quality of education over there,...and you are done...i mean after that a clear choice can be made...and if you want to try at other renowned places too, i may suggest you....
Maharaja Agrasen Instof Tech, Delhi
Lovely Professional University, Phagwara
Jamia Millia Islamia, New delhi
Manav Rachna College of Engg, Faridabad
