Choosing either Kirori Mal College or Shaheed Bhagat Singh College depends on your convenience and future plans. Both are quite reputed. I have a few friends from SBSC and their experience with the college has been great. 

Here are some of the highlights of SBSC.

• SBSC has a great placement record. In the recent placement drive, the average CTC offered was 3.5 lakhs and the highest CTC was 18 LPA. 
• The college has a number of societies and committees that you can join.
• SBSC has the best Commerce department on the south campus. It is in fact among the top 10 Commerce departments in DU.
• The student crowd is friendly.
• The faculty members are great. 

Overall, SBSC can be a decent option for pursuing your B.Com degree. However, you should always give preference to the course over college. So, choose the institute that offers a better program for your choice of course.
