Hi,

You should go for IIIT. This College is too  good in terms of placement and academics. LM institute of information technology and SGSITS are  good institutes but still they are private institutes and not comparable with IIIT. Well, I think IIITs have a good reputation than SGSITS & LNMIT as far as their academics are concerned we can treat them same but IIITs are more better in reputation .

As far as my opinion, you can choose IIT-BBSR over SGSITS and LNMIT.

Both of these colleges are really good. The infrastructure, faculty and placements are great for CSE. However, I would suggest you IIIT Bhubeneshwar  due to a better location and it is improving in its standards. It  would give you better opportunities for internships and placements.

Now, the final choice should be taken by you on weighing all priorities.

Hope this helps.

All the best.
