As far as the course B.Com (Hons.) is concerned, both the colleges, Gargi or SBSC are good in their own ways. 

The Faculty of both the colleges are well experienced and cooperative. The only difference is that Gargi is an all girls college unlike the other. 

If you want to choose between them, it is preferable you go for Gargi. Being a girl's college the experience you will be getting there will be quite different, considering the ambience. 

SBCS is also good but Gargi has better placements, as many top companies take part in their placement program. Gargi also has a better position in DU in terms of Drama, Debate, cultural programs, extra-curriculars, etc.

Therefore if you want more exposure from the college both in academics and extracurriculars, then Gargi would be a better choice.

According to the reviews online, Sri Guru Gobind Singh College of Commerce (SGGSCC) is a very well maintained institution. They have a proper infrastructure with a good faculty and student crowd. Shaheed Bhagat Singh College (SBSC) is also academically a good institute. 

It is suggested that you do not go for Dyal Singh College (DSC) but opt for anyone among the other two mentioned.

Between SGGSCC and SBSC make your choice based on the location. If you belong to South Delhi, Noida or Gurgaon, then choose SBSC. If you are from any other part of Delhi choose SGGSCC. 

If you are from an outstation choose SGGSCC as overall living cost in North Delhi is cheaper than South Delhi and you can also stay near North Campus which will help you interact with a much more diverse set of people.

Choose KMC or Ramjas college over SBSC because these are better options. When it comes to academics KMC and Ramjas are definitely better than SBSC. There are reasons why the required cutoff for these colleges is more than SBSC. KMC and Ramjas also have better rankings. Many times these colleges were featured among the top 10 colleges in India. Also, if you want to pursue higher studies like M.A in Economics from DSE, then being from DSE will help. As the student crowd is more competitive at the north campus.

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. 

Among the mentioned two colleges, Shaheed Bhagat Singh College (SBSC) will be a better choice for B.Com (Hons.). 

• It is well known for its commerce courses. 
• It is considered the best commerce college of Delhi University. 
• B.Com is really good here with proper academics and placement records.

Dyal Singh College (DSC) is good but when compared to SBSC, it is more of a second option for commerce students after SBSC.

Both colleges belong to the same league. However, for a B.Com degree, Shaheed Bhagat Singh College is better. It has a better faculty base for Commerce. It also offers better gender diversity.

Although JMC has good faculty for B.Com, it’s not better than SBSC. JMC has a vast campus but there are not many hangout places or food joints, etc. Overall, SBSC is definitely a better option for doing B.Com.
