Hey,

BMS from DU is one of the best course to pursue if you're planning to do MBA from premiere BSchools.

Given options between KMV and NMIMS then you should always go for KMV.

BMS of DU is a very well known course and gives a lot of exposure of business and management. Also, BMS from KMV, DU cost less than BBA from NMIMS. KMV is a very popular college and ranks top 3rd in BMS courses whereas NMIMS is only famous for its MBA course and not for BBA.

Among all DU is a centralised university whereas NMIMS is private institution and is not famous for it's undergraduate courses. Also, Placements at KVC is much better than that of NMIMS.

Hope you a make right choice for yourself! 

Good luck!
