I'm a accounting student, for my own opinion I would suggest you take Accounting because it is a professional and specialize programme which mean u required a special knowledge and skill only can conduct the work. Yes, u might can say audit firm will accept Econ, Finance and BBA graduates to work as audit associate but in long term Accounting Degree student are more advantage because their increment and promotion chance will be more than non-accounting graduates. Beside that, the firm will require you to take professional exam like ACCA if u want to get promotion.

I would like to say what u have study in f6 econs is totally difference in what you will study in university. Degree in econs is not a memorizing course it is a understanding course not like f6 level u memorize it u can score it.

In addition, if you are just a normal econs graduate u might hardly to get a job after you graduate because your course is quite general so you might need to competitive with BBA and finance graduates. Unless your econs degrees have offer you second major like actuarial science or double degree with accountancy then you can take econs.

P/M: Last time, when i finished and received my STPM result I am faced the same problem with you. I'm lucky have a person to share me his experience after that I decide to do accounting.
