Which course is best to do from NICMAR that has better future aspects?

At NICMAR, there is no such thing as the best course. All courses are at par in terms of job profiles, packages, recruiters, and others. However, PGP ACM is the flagship program by the institute. 

PGP REUIM course recorded stellar placements in the past year with the top recruiters like KPMG, L&T Realty, Oberoi, PwC, Samsung, and CBRE. Recently, even PGP IFDM students had performed exceptionally well.

In the end, it depends upon your knowledge and skills. Decide based on the course curriculum rather than peeping into the placement statistics, as it is subject to the caliber of the batch each year.
