It is suggested that you go for Delhi College of Arts and Commerce (DCAC) rather than Dyal Singh College (DSC).

Here are some reasons why:

• If you want a college with better infrastructure and canteen opt for DSC. 
• On the other hand DCAC provides excellent Extra-curricular activities, societies, clubs, placements and overall exposure.
• The faculty of both the colleges are good. DSC is better in B.A subjects but not economics.
• DCAC has better connectivity. It is near to metro stations on the yellow line and pink line. Whereas DSC is only close to JLN stadium metro station on the violet line.
• Neither of the two colleges offer hostel facilities. 
• But it is easier to find accommodation near DCAC than to DSC.
• Accommodation near DCAC is also affordable.

Therefore overall DCAC is a much better choice. But in the end it depends on individual preference. Try visiting both the colleges, explore, talk to the alumni or faculty members, if possible and then take the decision.
