My friend studied at IIEST Shibpur but it was a long time ago. The quality of pedagogy back then was good, however now one can't say much of it. Also personally, CS does not have the best faculty in AMU.

If you wish to compare the state of teaching in the institutions, just log in to the official website and go through the qualifications of the faculty members. Check both the academic achievements of the faculty in general, as well as that of the departments.

If you live near Shibpur then it'll be easier to commute, however, if you live far away then you can choose AMU. You must note that IIEST Shibpur's IT department might have to shut down and you may regret your decision during placements.
