First of all, you need to understand the difference between BBA and B.Com and then select a course accordingly.
Delhi University
Pros: Brand name, good academics, good Fests and societies. No attendance issues.
Cons: Bottom colleges are decent in terms of academics and placements.
Maharaja Surajmal Institute
Pros: Reputation, discipline, great academics and good placements.
Cons: Attendance issues.
To sum it up, if you're planning to pursue CA/CS/IAS, etc., along with your graduation then I would recommend Delhi University as it has less attendance issues plus shorter duration of classes.
Otherwise, if you have no such intention or you get a bottom college of Delhi University you may consider Maharaja Surajmal Institute as it's an equally reputed college with good academics.
All the best.
