How do IIT Delhi/Bombay, BITS Pilani, NSIT and IIIT-H compare?

Placement-wise, IIT Bombay is clearly the winner, followed by IIT Delhi with IIIT Hyderabad and BITS Pilani almost similar 

Courses: Course-wise too, IIT Bombay wins the race accompanied by IIT Delhi, IIIT Hyderabad, and BITS Pilani subsequently.

International competitions: The order remains the same except BITS scores better than IIIT Hyderabad in this aspect.

Startup culture: The startup culture too is best at IIT Bombay, then IIT Delhi followed by BITS and Hyderabad.

\Alumni: IIT Bombay has the highest number of successful alumni across the globe after which stands IIT Delhi, BITS Pilani, and finally IIIT Hyderabad.

I don’t think it’s logical to compare extremely old and government-funded IITs with private institutes like BITS and IIIH. The alumni reach is also incomparable.
