Hi,

All three are good Institutes and two of them are Institute of National Importance. ECE is the most popular branch after CSE and IT. Among these three, MY first choice would be IIIT Trichy. IIIT Trichy has NIT Trichy as it's Mentor Institute. This will give more career opportunities for the students of IIIT Trichy. The second choice would be IIIT Kottayam and third choice would be IIIT Bhuvneshwar.IIIT Bhubaneswar is not a National Institute of Importance but it is a State University, while IIIT Kottayam is an Institute of National Importance. IIIT Kottayam Reputation will improve in the coming years .

I hope this will answer your query.

Thanks!!!
