Hello Akash. NITs and ICT Mumbai all are considered to be the top colleges for engineering engineering in India. 

At the time of comparison, top NITs such as NIT Tiruchirapalli or NIT Silchar are considered to be a better option. However, in comparison to some NITs such as NIT Calicut, you should choose ICT.

So, unless it's a top NIT, you shouldn't leave ICT Mumbai.
