Hello aspirant,
Both were the renowned institutions of India. You can have a very good experience of learning and exploring new opportunities in any IIT's.
But firstly you have to choose your own interest in the field of CSE or ECE. As college just provide you knowledge but your interest will help you to learn extra skills on that topic, thus creating chances of getting higher packages.
