This is a good question. ABM or Accounting, Business and Management is a education course well suited for students looking to enter the corporate world. ABM is such a general realm of study that you could do a number of things. So there is no "Best" from a general standpoint, but there certainly could be a best for you individually.
To help determine what would be the best for you, try considering the following:
1. What are your income requirements? Some jobs might be more fun, but if they don't pay the bills they are not a sustainable option.
2. What are you most interested in? -Finding a job that aligns with your interests can help stave off burn out and keep you engaged
3. What are you long term aspirations? - Some jobs can be career limiting - knowing this ahead of time can save frustration
Best of luck to you!
