Hello,
All of the above college belong to Institute of National Importance and since they are new, they are continuously developing.They do not have their own campus yet. And some do not have had placement seasons too.
So considering all the above factors as per me:IIIT Kota~=IIIT Vadodara>IIIT Surat>IIIT Kottayam.
