Dear Subhajit, 

First and foremost, since hotel/hospitality sector is work-intensive sector, it becomes very crucial to get some training during the study period itself so as to give yourself some exposure to the industry standards and working style. So, you should always look for a degree which can offer you some practical training, and especially so if you are planning to work on-ground after completing your degree. 

Secondly, fundamentally, an MBA degree should give knowledge of business administration and management, while an MSc degree is comparatively theoretical in nature which is apt for those seeking to go into advanced studies in the form of MPhil, PhD or teaching. 

Finally, when it comes to pay package, etc., much more than your degree, would count the skills and knowledge you would have by the end of your degree programme. So, go for a degree which can give  you the understanding and skills required for the industry. 

You can consider these aspects, before choosing between these options. 

Hope it helps. 

All the best!
