I think Vit is good.There are lot many things good about VIT:

• Diversity of students; makes you comfortable when you come out of university.
• Knowledge ; It depends on how you manage to grasp and how you involve in the subjects.
• Placements: I feel VIT is much better in getting opportunities to students as lot of tier-1 companies comes. (Personal Experience)

It doesn’t mean that all other institutes are bad. As far as I know, VIT is good among all you mentioned above.

If u have a choice to select among these, Go ahead with VIT.
