Why is it that IIIT Bangalore students are the only ones who consider IIIT Bangalore to be among the top institutions?

I am assuming you mean this for its UG programs. IIIT Bangalore is highly renowned for its PG degrees.

The institute is popular among academia and industry. However, it isn’t popular among students who are fresh out of school. This is because its UG courses aren’t that old. However, many students still opt for IIITB because of the huge potential of its undergraduate programs. 

In practice, IIITB has a lot to offer. Students begin appreciating it upon experiencing the campus culture up close. It offers top notch faculty, curriculum, peers, labs and industry connections. CSE/ECE students get ample opportunities and facilities for their all-round development. Its integrated courses are performing well and making a mark with each passing year.

IIIT Bangalore is a strong competitor in PG studies, and making steady progress with its integrated programs as well.
