Hey there!

IIITs have the have a great curriculum for coding because the institute is primarily devoted to that. It is a government-private institution with NIT Kurukshetra as the mentor institute. Both colleges you have mentioned are really good but I'd recommend IIIT to you because you want to pursue computer science and IIIT is mainly for that. Choose according to what you are looking for as it's your decision at the end. All the best.
