Hey,
Both Bachelor of Commerce (B.Com) or Bachelor of Business Application (BBA) are good at their respective places. So it entirely depends upon your calling and interest.
B.Com or Bachelor of Commerce is a three-year undergraduate programme which can be pursued as a full-time and part-time course. It equips the students with the knowledge of Commerce and finance.After B.Com you can make a career in accounting,finance,banking and insurance.
BBA or Bachelor of Business Administration is a three-year professional undergraduate course in Business Management. After BBA you can work in the field of Marketing,Banking,Business Consultancies,Government sectors etcetra.
Hope this helps.
Good luck.
