So top 5 IIITs are Hyderabad, Bangalore, delhi, allahabad and gwalior
And top 5 in josaa would be allahabad, gwalior, lucknow, jabalpur and kancipuram
So, after eliminating above option, I would still not recommend VIT vellore instead I would recommend IIIT guwahati, IIIT kurnool, IIIT pune and IIIT sonipat and IIIT bhuvneshwar and IIIT vadodara.
Reason behind is
- IIITs have INI(institute of national importance) tag.
- Number of student in CS branch. IIITs hardly have 150 to 200 students in CS where as VIT alone have students in thousands
- Fees which is also a major factor. For example my friend in VIT vellore is paying around 22 lakhs for CS degree where as I am paying only 8 lakhs Rs in IIIT gwalior
- Above mentioned IIITs which are new are mentored by top IITs , NITs and IIITs.
