What you like the most matters. If you are leading scientist or a researcher then also you get a lot of respect. If you go for phD then you will be able to add the Dr. prefix in the name. But this are not important. The important thing is that what you enjoy? You need to find it out. If you think it would be better for you to be in a hospital then go for it. But if you feel really amazed and proud to be infront of a telescope and watching the night sky for the whole night and figuring out the dynamics then you should go for it. See you have to decide that what is important for you? Either ways you will get the respect but in one way you will get the best satisfaction which you need to discover!!.

Now if you are very confused then you can choose PCMB if its provided by your institution.
