Hi, since both the colleges are owned by state government so in college comparison KNIT has an edge over Dr. Ambedakar Institute of Technology for Handicapped, Kanpur. Now since it have an edge over  Dr. Ambedakar Institute of Technology for Handicapped, Kanpur so if we compare both the branches that you have asked in the question so on the basic overview of the both the ECE of KNIT and CSE of  Dr. Ambedakar Institute of Technology for Handicapped there also ECE of KNIT have an edge over the other institution not only in placements but overall development also.

Good Luck.
