Hello Rajeev,

         Coming to IIT bhu and Hyderabad I say that IIT Hyderabad is the best. It has best teaching faculty and good administration responsibility which make students afford good results. Where as BHU has a very good campus life they involve students in many social and extracurricular activities...

I want to give you some comparisons so that you can decide for yourself

1. Academics-IITH>>>BITS>IITR>IITBHU

2.campus life-IITBHU>>>IITR>BITS>IITH

3.Placements-BITS~IITR>IITBHU>IITH

4.People sitting at the top positions have graduated from these colleges are-     IITH>IITBHU>IITR>BITS

Hope this information helps you out to decide for yourself

All the best.......
