Hi Abhay!! Hope you are doing well!! NMIMS is a very reputed College and it has been rated A+ by NAAC. It has great resources and good materials for studying mba. Welingkar is also a goo College, but it doesn't have good reputation compared to nmims and it also has loweer placements than nmims . Nmims has a great placement records . So I would say, nmims would be better for mba course.
