Hi,

Among these three colleges, NIT Durgapur is far better college than other two. IIIT Sricity and IIIT Kancheepuram both are newer IIITs but NIT Durgapur is one of the prestigious NITs. If you are getting CSE in NIT Durgapur then you should take it. Since you belong to south, you will feel unfamiliar with West Bengal culture, but that would be Only for few days. Once you make friends, you will get mixed up with everyone from college.

Thanks!!!
