Hello, 

Well, the perspective differs from person to person.. According to my point of view NIT Sikkim would be a better choice for CSE branch.. 

The faculties are good and focus on providing quality education to the students.. Most of the Faculties are highly educated. 

The placements are good for CSE branch.. Also, famous companies like Microsoft, Intel, Infosys, Wipro, etc visit this college.

Overall, NIT SIKKIM would be a good choice among any other.

I hope this would help you. For further queries please feel free to write me down in the comment box.
