First of All, all 3 of these are private universities with their main campuses in South India. Out of these 3, the one which i personally recommend is VIT , it is because it has a good reputation of all 3 of these and even it's two B.Tech fields have got International Accreditation from ABET and even there are education tours outside India developing every bit of a child.
I am telling u VIT because of three points,
1.It has a very good placement option specially this year it has set a record of many placements, you can check it out on VIT website- http://www.vit.ac.in
2. International Accreditation is a great achievement for any university.
3. It's programmes for Students are the most suitable giving every bit of time to carry on all the activities.
4. There is full support for all leisure activities.
And hence from all these a student can succeed in himself, as there are three keys to success- work, play, keeping everything up to yourself.
All the Best
