Hey !

 There are many factors a student consider before taking admissions to any college. So , j would suggest you to go for NIT because of some of the basic reasons like NIT has obviously more national importance , it has a much better  reputation than JNTU . So , unless you are getting a seat in NIT , don't go for JNTU .

You should go for NITs like NIT rourkela , NIT warangal , NIT surathkal , NIT nagpur etc.

It all depends upon your rank , whuch NIT you are getting with that rank.

You can also compare both thd colleges using following link:
