Hey jahnavi

VIT is much better in any terms . There is no comparison !!
Placements : some students got 3 company offer letter .
Infra : One of the best campus in india .
Faculty : Do self study .

But if you are having interest in bioinformatics than yo can go with sastra no problem at all.It is also having a good reputation.But you will be getting good placements in cse at vit if you will be having skills.

ALL THE BEST
