Hello,

I would suggest don't go by NIRF because in NIRF rankings there are many other factors taken into consideration other than placements before deciding the ranking so i would suggest just go on your liking . If you like IIT Bombay then go for it and if you like DELHI then go for it.

As you are opting CSE branch there won't be any difference in opportunities because both these top level IITs so i would suggest that just search for both these colleges and choose the one which fascinates you.
