One of my friends from high school used to be a student of IIITDM Kanchipuram and in his opinion, ECE at that institute has a far better system of progressing with the course than the NIT system.

IIITDM Kanchipuram also boasts of having a superior faculty. IT has also been derived from the ECE. Both hardware and software are involved in ECE. So, if you are more inclined towards Physics and Maths, go for ECE.

Thus it is suggested that you go for ECE at IIITDM Kanchipuram than IT at NIT Raipur. ECE also has better scope and opportunities than IT. Graduating with ECE you can sit for placements of both core sectors and corporate sectors.
