Hello aspirant, 

NIT Goa and Vjti Maharashtra both are government colleges, nit is approved by UGC and vjti is approved by AICTE, both are good in infrastructure and facilities. Students is to faculty ratio is acceptable in both. Faculty is good and experienced. And, coming to the most important factor that is placement, in vjti placement records are increasing year by year now it has come to 92% but placements are only good for CS branches it has no good placement for ECE in core companies. And when it comes to nit it has somewhat placements for Mechanical. 

Hope it helped to clear your delimma.
