Hello Abhishek, 

For MBA if I compare these two colleges, of course UBS Mumbai will win the battle. UBS Mumbai have very good faculty team and placements are excellent. They have tie ups with so many foreign universities. Infrastructure and other facilities are excellent in UBS, Mumbai. Criteria for admission in UBS is slightly tough as compared to Jaipuria. UBS also provides foreign placements to the students. 

Jaipuria is an average college with average placement record.

I hope this will help you.
