Hi

NIT raipur is somewhat better than the rest two, i.e. IIIT Naya Raipur and Bangalore Institute of Technology. It is further an institute with decent placements as compared to these. Also, as compared to these, it has a decent NIRF Ranking too, which IIIT Raipur does not have.

Still if you have an inclination towards a certain branch which you might not get in NIT Raipur, then go for it. Interest of study in students is one of the biggest criteria in choosing a right college and branch for the student.

If you feel to study CS then choose Bangalore Institute of Technology. If AI then IIIT Naya Raipur. Or if you don't prefer any, then certainly go for NIT Raipur.

Best of Luck.

Hope this helps.

Cheers!
