Hello Mayank,

Congratulations for making this decision.

According to me nit silchar is more developed than nit Agartala. We can compare them on many basis -

1) Campus-  Both the campuses are very good but nit silchar has edge here. You will find that nit silchar has better campus life including all facilities, mess , library etc.

2) Academics- This is actually good in nit silchar. Nit Agartala does not have very good faculty. In nit silchar you will find good teachers and also you will be having more scope to go into research there.

3) Placement- Nit silchar has far better placement than Agartala. This is because of the remote location of nit Agartala. Almost all big companies visit nit silchar but not Agartala. Alumni base of both the college is good. 

I strongly suggest to go for nit silchar
