Hello,

Thee best campus is the Hyderabad campus it is being one of good B- School with good ranking. According to rank it would be:
1. Hyderabad
2. Mumbai
3. Pune
4. Gurgaon

Among all the campuses of IBS which is located in Mumbai , Pune , Gurgaon & Hyderabad premises during the the time counselling I think you should go with the option Hyderabad campus because for doing the course in the Hyderabad section will make you stand elite as well I heard from most of the aspirants that facility in the Hyderabad section is better including all the major one.

Hope this helps, Good Luck
