Why is CSE at IIITD considered better than CSE at NSIT?

NSUT Delhi is known for its COE (Computer Engineering) course.

The COE course is different from CSE. In COE, you will study hardware, electronics & signals, and codes & algorithms. Unlike CSE, software is not the main focus of study in COE.

Now as far as a comparison between them is considered, IIITD has a much better teaching environment than NSUT Delhi. Though it also has an experienced faculty, you will mainly be taught by Ph.D. students during the first two years.

Unlike before, however, the NSUT Delhi curriculum has been updated. There is now a CBCS (Choice Based Credit System) and you won’t have to compulsorily study unnecessary subjects. Both institutes have a pretty good placement record. Although the COE branch concerns itself more with hardware, students get placed majorly in software profiles. 

All I can say is that NSUT Delhi has now an updated curriculum and a university status. On the other hand, IIITD is a comparatively new player in this field that is also performing quite well. Thus, both institutions are a good choice to pursue your computer studies.
