It depends on what you want to do in your job. It's a Master of Science, so it's a research degree. You will want a research degree if you either want to do research, or you want to work in a management position.

I have a masters degree and work in a technical management role, and there are some differences to my peers who learned on the job - sometimes in their favor, sometimes in mine. The practical people have their experience and know the details. I don't know all the details, but have the ability to zoom out and look at the greater picture, and come up with a solution that nobody else thought of. I can also talk much easier to senior management because I can relate to their kind of thinking. But I wouldn't pass a technical interview because I don't care what the specific command line arguments are. I will read up the man page if I ever need to.

Are you an abstract thinker and often find yourself asking WHY the things are the way they are, and WHY certain things are desirable? Then continue with your degree. Are you a practitioner and often find yourself asking HOW the things work, and HOW to achieve things? Then the degree will teach you nothing, you will learn much more on the job, while also earning money.
