Hello

I will give you a short comparison of both so that you yourself can decide which one suits you the most.

NIt Nagaland, has been ranked 91 by JEE CUTOFF 2019 for enginering. Depending upon the coure the average package may vry from 6 to 10 lakh per annum. The education level is great with well qualified and helpful teachers(mostly from south india) and the course curriculum is good, relevant and to mke the students industry ready. The food is not that good, speially if you are a vegetarian. It has it's own  hostels, classrooms, administrative building, library etc

JNTU Karimnagar- It has less than 70% placement records (vary with the subject taken) with the highest salary offered for cse department being around 6 lpa. The infrastructure and faculty is good and the course curriculum is good.
