Among these two, IIIT Dharwad will be a better choice. Here are some reasons why you should choose IIIT Dharwad.

• It is an institute of national importance. It is run by the Central Govt. on a public-private partnership basis. Selection for admission is merit-based on an India basis.
• The location of the institute is better in terms of placements and getting internships and practical learning opportunities as compared to IIIT Raipur.
• The only point of disadvantage for the institute is that it does not have a permanent campus. But that should not matter if your branch is CSE or ECE.

Here is a brief highlight of IIIT Dharwad.

Not having a permanent campus will not be a big issue, if you are not that into extra-curricular. From an academics and placement point of view, IIIT Dharwad is definitely a better alternative.
