Of course VEERMATA JIJABAI TECHNICAL INSTITUTE ie VJTI only is the best state government engineering college in Mumbai after IIT. It's a very well known college which has great placement opportunities and almost 100% placements possible. SPIT is also another great GOVERNMENT college but it doesn't has CS branch in it if you want to pursue CS which is the most upcoming branch. If you getting CS in VJTI then it's the best scenario, and if any other engineering like electrical, mechanical or civil, etc then any of these 2 government colleges of Mumbai will do.

Best wishes. Thankyoj.
