Which one should I choose, NSIT CSE or NIT Surathkal IT branch or MNNIT Allahabad CSE knowing that I stay in Delhi?

Few of my friends study in NSIT COE, who have left top NITs and CSE programs for NSIT COE. 

In the following table, you will get the basic information about NSIT CSE, NIT Surathkal IT branch, and MNNIT Allahabad CSE.

The following points will give you a more clear picture of the institutes:

1. Location: NSIT is located in the capital city of India. This gives plenty of opportunities to students to get placed in top companies. All the top companies come for a campus placement here. You can also visit nearby places on college off days.
2. Placement: The placement record of the COE branch is very good. That makes the cut-offs high. Also, the culture of coding in NSIT is pretty serious. You will be every second student doing the coding.
3. Opportunities: There are various institutes in Delhi for CAT/GRE/GATE, that will help you in clearing these exams. Also, there are various coding institutes like Blocks, Coding Ninja, Pepcoding, etc. These will help you polish your skills, and help you secure good packages.
4. Near to Home: You can also enjoy your hostel life and home life. During exam days, you can visit home to concentrate on your studies. 

Therefore, if you are thinking of joining the Netaji Subhas University of Technology then go for it. As there are several advantages of joining the NSIT COE branch. Also, in the long run, your skills matter, not from which college you have studied.
