Dear Jack Dawson,

                            Both the branches are really good but if you compare the branches then generally the closing rank for chemical branch is very high so it means the branch is very good than the metallurgy..but if you compare the IIT...IIT kanpur always stood top position among all IIT's in placments and infra structure i.e.,labs and all..we had a flight lab over there so once we wnet over there the labs for AEROSPACE branch in IIT kanpur is really wow than the bombay..like that for evry branch Kanpur campus has really super good facility in labs like Research n development..so if u give importance to branch means then go for chemical dual in Roorkee bcoz very good plamcnets than the metallurgy branch...but if you give importance to IIT means then go for Kanpur..but as per me i suggest Kanpur campus..
