Hi, it is recommended that you first choose your branch. Looking at the pattern and future opportunities in both the branches there is minimal difference between them. IT is all software based and CSE is Software, Hardware and OS core based. Coming to colleges. NEHU has larger space and better infrastructure. Also NIRF ranking is around 82. So, NEHU is better. You can compare your colleges as well as the branches on the link given below. Hope this helps.
