Hello dear ,

VIT's infrastructure is better than JIIT's . VIT is the one of the best university for Btech in INDIA . VIT has many other btech and science programs that has good placement records for those branches .  The branches like Computer science and engineering is still improving in JIIT .  The placements in VIT's are also recorded good .Almost  90 % of students are surely getting placements with good salary offerd .

So , VIT would be better choice .

Good luck !!
