MBA in hospital management is a good choice if you have a life science background like MBBS, BDS, BAMS, or even B. Pharma. Yo can take the job of hospital aiministrator, insurance sector, health care IT, hospital industry marketing, etc.

MBA in marketing is comparatively better than hospital management. It's good for those who have good mathematical ability, good communication skills, analytical, leadership skills,etc.
It basically depends on your choice of interest. Go through the placements of the specific college in both the branch and then come to a decision. Both the branches are well and good at their own position.

Good luck!
