dear aspirant,

According to my knowledge NSIT and NIT bohal both are very good college .

Placements in NSIT are very good , but in nit bhopal in ece placements are good but packages offered in ece are quite low in comparison.

NSIT has a beautiful campus and Delhi being the City of opportunities , you will get a good exposure.

Rest all depends upon you, select the college as per your convinience which ever suits you.  Both the colleges are euqally good and ranked amongst top colleges in india.

good luck.
