Hello Chatterjee

NIT Durgapur and NIT Nagpur offers 8 courses in CSE both but NIT Surat only offers 6 courses ,NIT Durgapur and NIT Nagpur has a better rating in college than Nit Surat, the fees for all 3 lies between 5.50 lakh to 5.60 lakh , all 3 have equally good facilities,it's easier to get admission in Nit Durgapur compared to NIT Surat and Nit Nagpur and the median salary for 3 is around 6 lakhs per annum so if you are from Bengal get into NIT durgapur as it will be close to your home because all 3 are pretty much the same . I will attach a link for college comparison where you can check it yourself and even compare more colleges
