Is iiit Sri city or iiit kanchepuram is the best? 

Dear Biki,

IIIT, Hyderabad is renowned for CSE and is regarded on par or even better than IITs for this department.

As far as IT Department is concerned, IIIT Hyderabad is the best while IIIT Delhi and Allahabad are considered to be the next best among them.

For ECE, IIIT-Hyderabad and IIIT Allahabad are regarded to be the most reputed ones among all other IIITs as ECE curriculum is imparted to the students right from the first semester and also the colleges give a very great coding exposure to its students.

Hope this helps!
