Thanks for A2A.
Look if you are interested in Computer Science and Coding then I will recommend you to choose IIIT Sri City. Though they are new just 4 years but you can see that they are increasing in very high speed here is one of my answer related to IIIT Sri city why you should prefer it as compared to other IIITs: Prithivi Kiran’s answer to What should be the order of these IIIT for CS/IT branches?
IIIT Sri city Mentor director is Prof. U. B. Desai – Wikipedia who is also director of IIT Hyderabad . You can click on the link to know more about him.
As compared to VIT , IIITs are better if campus is not considered as they are new . So in the coming 2–3 years these 2 IIITs will surely be ahead of VIT in all aspects in campus also.
The order should be :
IIIT Sri city > IIIT Guwahati > Vit
