Which college is best among NIT Delhi, NIT Kurukshetra, and SVNIT Surat for CSE if my residence is in Delhi NCR?

You need to consider several factors before deciding the best college for yourself. Here are a few factors and the preferred choice if you give preference to that factor alone

1. Alumni : The age of the institute determines how strong the alumni network is which is very crucial for the development of the institute. In terms of the alumni network the preference order should be NIT Jaipur=NIT Kurukshetra> NIT Delhi
2. Placements: The placement scenario is somewhat similar in all the aforementioned institutes. However, NIT Delhi has a slight advantage being in Delhi. The order should be NIT Delhi > NIT Jaipur = NIT Kurukshetra
3. Faculty: In my opinion, NIT Delhi has the best professors.
4. Campus : NIT Kurukshetra and NIT Jaipur have equally beautiful campuses whereas the permanent campus of NIT Delhi is under construction.

Ultimately, the final decision depends on your personal preferences.
