These are basic graduation courses and scope wise it depends what you are interested to do in your masters.
The B.Com and BBA has its own merits. Most of the students get into commerce stream with no understanding of what it involves. However, if management is ultimate goal, though both BBA and B.Com will lead to MBA, but one needs to give it a serious thought as to what subjects to graduate in even if the ultimate goal is MBA.
So you have to decide what your future goal is.
Hope this helps.
Good Luck.
