Among the choices, IIIT Vadodara is a better alternative. IIIT Vadodara is established on Public-Private Partnerships based on the Government of India. It is an institute of national importance under the IIIT PPP bill.

It is running under DA-IICT which provides the best facilities at least in terms of academics. It is operated from the Govt Engg College, Gandhinagar on a temporary basis and soon will be operated from its very own campus. The permanent campus will helpful in the extracurricular domains and apart from that, all the facilities are provided at the Gandhinagar campus only.

Here is a brief overview of the two institutes.

Hope this helps you in making the decision.
