Vikas, MBBS is a professional Medical Degree and MBA is a Post Graduate Degree in Management. There is no comparison between both of them. For studying MBBS, you should have completed your 12th in Physics, Chemistry and Biology and appear for NEET. You can work as a Doctor either with your own practise or in Super Specialty or Multi Specialty hospitals. You can also study MD/MS to  become a specialist in any particular field of Medicine. MBA on the other hand is a Management degree which allows you to work in various sectors. With enough work experience, you can move up the ladder to become a Manager in the field of specialization that you choose to study your MBA in. But to answer your question, MBBS is the better course for the outreach, opportunities, fame and reputation.
