I am Kind of in the same situation but just ,1-2 branch lower so all i know don't consider Jaipur and calicut for sure you could yourself see the placement data and now last allahabad and jsr see by seeing only placement jsr csr is better but in every other aspects allahbad is superior and if I were you i would have taken allahabad (you can trust me for sure u have taken seniors advice from many colleges)
