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.

It is suggested that you go for Sri Venkateswara College (SVC) or Sri Guru Gobind Singh College of Commerce (SGGSCC), as both colleges are famous for their commerce department. 

They have the best, most experienced faculty with some professors having 15-20 years of educational experience. You will have opportunities to take part in extracurricular activities through clubs and societies. SVC also has the best placement opportunities and has the advantage of being in Satya Niketan, the best college of south campus.

Therefore, your first choice or preference should be either SVC or SGGSCC, followed by Ramjas college.
