IIT Ropar - Indian Institute of Technology Answered Questions

See, for CSE branch, IIT-Ropar is better than the DTU as the faculty of the IIT is much more qualified than the faculty of DTU, in IITs faculty are double Ph.D and also they can offer you a letter of recommendation that you will be needed if you want to do your Master's degree abroad.

All the mentioned institutes occupy place in top colleges in India DTU and nsit would offer high chances to get placed with a good salary as they are located in capital city that offer proximity to HQ of various firms. IIT Ropar offer a brand IIT associated with it that would be helpful if you wish to go for higher education moreover ropar is now 8yrs old and do have a decent alumni base that is helping the institute with the high placement offer but not all companies visit ropar that are on list of DTU and NSIT. Between NSIT and DTU, DTU is a huge alumni base that would help you in future and ED cell also offer huge incentive for the young minds. But down the line 4 years Ropar would surely outstand NSIT and DTU since the central funds are directed more to IITs.

Don't know about IIT. NSIT and DTU are equally good, but since NSIT has lesser students, and companies visiting are almost same for both, you will find less competition in NSIT. If you are good at coding, then both have great opportunities for you.

No doubt that IIT are always better institutions than any other engineering colleges. They provide you the best environment for study and research. Our Indian government also focus on these IITs in order to make them centre of excellence and promote research activities there.
So according to me IIT Ropar should be prefered.
