Hello Animesh

If you can get VJTI then it is really good other than IIT or NITs. When you say that you want to do Mtech then u have decided to make ur career in technical side rather than doing MBA after engineering.

Doing mtech from any of IITs/NITs will always be best choice available. But I would say if u really want to pursue mtech and u don't have good rank to secure place in IITs then VJTI is next best option available in Mumbai.
