The overall campus life, peer group, brand name you'll get at iit is unmatched anywhere else. Sure, if you wanna look at only one aspect that is placements, then both colleges are comparable. But when it comes to overall experience, exposure that one gets, etc iit kanpur is miles ahead of iiit Hyderabad. Don't just look at that shiny cse degree. Other things such as campus life, exposure to varied disciplines matter too. I myself graduated in cse from 2nd gen IIT. From my pov, in your case, iit kanpur wins by a mile. You can ask any doubts if you have.
