What should I go for ECE in Bangalore Institute of technology or CS in AKG College of Engineering, KIET, ABES, Galgotia?

CSE in AKG and ABES will be the best choices. After these, Galgotias and KIET are second best options.

If you do not have a strong preference/inclination for a stream, go for BIT, no doubt. It has a NIRF ranking under 100, a great location, collaborations with great universities whereas AKG, KIET, Galgotia don't come anywhere near. Do upvote if you like the answer.
