Vadodara

When the comparison is between IIITs and IITs, the war is always in favour of IITs whether it be any branch or stream.
The reason being the quality of students, management of IITs, the large-scale organization of events as well as technical and cultural fests from which students learn a lot.
Although, a IIIT may have a better infrastructure due to its late establishment but is overcome by the vibrant lifestyle of IITs.
Now coming to the placement statistics, the average there at IIT Guwahati is around 18 lakh per annum whereas 12 lakh from IIIT Vadodara.
Also, the highest package ever from IIT Guwahati is around 92 lakh in google whereas is 27 lakh from IIITvadodra creating a huge difference between the two.
Now, one may get into IIIT through Mains and through advance in IIT.
Sincerely, there is a lot of hard work needed for getting into CSE for any of the IITs, NITs and IIIT, but the preference should always be given to the IITs than top NITs and then top IIIT. Although some IIITs are working exceptionally well up to the mark of IITs, which are IIIT Hyderabad and IIIT Allahabad.
Thank you. Hope it will help you.

Both the colleges are newly established in PPP (public private partnership) model. Now if you want to compare these two colleges you can compare using certain parameters:
1. Location: Sricity is not a very big city not so behind Vadodara.You may choose one which is nearest to you home town.
2. Infrastructure: Both the colleges are new and infrastructure is just average.
3. Quality of crowd: Cutoff for both the colleges are similar. Students of IIIT Sri City are bit talented. Mentor Institute of IIIT Sri city is IIIT Hyderabad so one can easily understand the importance of being there. Coding culture is good there.
4.Faculty and Placement: Both the institutes are equally in terms of placement. Stats may vary every year.
I will recommend you to choose IIIT Sri City over IIIT Vadodara just because of its mentor institute (IIIT H).
