To begin, you must reduce your college options; Symbiosis offers many colleges in and around Pune. SIBM is the best in this category, followed closely by SCMHRD (just for HR).
So, for the sake of comparison, let's stick to these two.
Long story short, SIBM and SCHHRD would outperform NMIMS in terms of specific placements, but NMIMS takes the cake in terms of total placement and legitimacy.
Symbiosis is a rather diverse but not particularly well-structured college campus, and the plethora of possibilities can lead to some confusion, particularly when distinguishing the cream from the rest.
NMIMS, on the other hand, offers selective courses and hence has a superior overall atmosphere.
Finally, in terms of fees and ROI, NMIMS easily wins.
