First, it depends on your interest level on the Branch. Next, is the duration of course. Are you okay to spend around 5+ years in the same course, and specialization at a stretch? If you are inclined to take up career in IT and Data-Science, Machine learning etc., then better opt for integrated course. ECE will be a bit tough, when compared to IT, and if you are very keen to go for ECE related jobs, then you can opt ECE from ISM. Keeping in view of placement opportunity and coding environment, it would be better if you to go for IIIT integrated course.
