See both the fields have a good opportunity in both research as well as industry sector. Although to get the best feedback from the subject you need to have a Masters atleast to get chance in R&D sector and other sectors. So depending on your interest you should choose the course but you must have a clear mindset that you need to go for Higher education in order to get jobs. Now if you can do PhD in the subject then you have a career which incomparable. But if you wish to go for any of the subject you atleast have to get a master or else you would not be able to get jobs after BSc.
