Hello Naga

NIC would be a better option because first of all it has an NIRF ranking of 178, got established  in 1946, while NEC got established in 1998 which is recently as compared to NIC. The faculty and placement and other facilities in NIC are way better than NEC. For other information about both the institutes, you can have a look at the given links:
