Hii abhishek 

I'll suggest you to go for a generalised MBA. Because of the following reasons

1-There are different ways you can establish creditiblilty in your firm and industry. You could volunteer for a project at work that stretches you beyond your comfort zone. 

2-stategic thinking

It helps to think outside the box things and weigh multiple options or solutions. 

3-better communication skills -MBA graduates often are better in communication. Being a better communicator is essential in everyday life. 

If you go for a generic MBA you can work for any firm rather than sticking around with a drawback. 

I hope I helped. Have any doubts don't feel shy to ask.
