How is Mtech in IIT Delhi compared to Mtech in IISC Banglore in Computer Science?

One of my friends had both options, MTech in IIT Delhi and MTech in IISc Bangalore, however, despite his hailing from Delhi, he chose IISc Bangalore over IIT Delhi. Some strong reasons which influenced his decision were

• The Institute has excellent research facilities and approaches second to no other engineering Institute in India.
• IISc Bangalore does not have a BTech program and thus the entire focus of the faculty resources, education, and resources are invested in the Master's program unlike IIT Delhi, where BTech is given more importance.
• IIT Delhi has a higher intake of UG students than PG students and they are given more preferences and attention than UG students.
• Being situated in Bangalore, the IT hub of India IISC has close ties with IT companies visiting frequently for some or other events or technical competitions
• Most GATE toppers prefer IISc or IIT Bombay over IIT Delhi and so do the companies offering placements.
• The overall ambiance of campus life is more tranquil in IISc Bangalore than in IIT Delhi which is an overly populated and polluted city.
• IISc is being recognized by foreign universities and one can pursue their Ph.D. with a degree from IISc.

All these pointers strongly inclined my friend towards IISc and he eventually completed his MTech from there.
