Yeah nit tag is valuable. But still I read many bad things about nit Sikkim. Due to location I think few company visit there.I m very very confused and it seems you are also confused. Anyways thanks  Let's see What God has planned! 

No Dear looking at the companies that visit both of these I suggested you NIT.Yeah hope for the best :)Stay positive.N good luck.

Thanks Dear!  You are good! My first preference would be nit sikkim. Hope after 4 years the placement there improves. Also I choose ece over cse because it has good scope in both technical and government field. Cse students can't give ies exam. God bless you! :)
