I have friends from both JMC and DCAC. Based on their experience, I will say DCAC is a better option. 

• The student crowd at the institute is diverse.
• Facilities at DCAC are well-experienced and helpful.
• It got high ratings from NAAC and India Today Magazine.
• The institute offers add-on certificates and diplomas in foreign language courses. 
• DCAC has great infrastructural facilities. There is a library with a great collection of books. There is also a gym and table tennis room on campus. The auditorium is equipped with special lights and sound effects. 
• DCAC campus has a basketball court, a volleyball court.
• DCAC is not that strict about attendance.

JMC is definitely a reputed college, however, in comparison, DCAC is better.

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. 

Jesus Mary College is a better option than Loreto College in CU. it offers a better peer group. JM College boasts of a brilliant faculty base. The professors are well-experienced and have years of expertise in their respective fields. It offers good infrastructural facilities. JM College has a 3-floor library with a huge collection of books. The departmental labs are well-equipped with latest technology. Many reputed companies such as Deloitte, KPMG, Royal Bank of Scotland, etc. take part in the campus placement of JM college. 

LSR and JMC both are reputed colleges. If we compare then LSR is definitely a better college than JMC. LSR is the best girls college in DU, followed by JMC. 

However, it’s best to choose the course of your interest over college. As the course will have more effect on your future. So, research about the course that you are interested in, in both LSR and JMC. 

In general, as a subject, Economics Hons has better scope than Statistics Hons. However, if you are interested in numbers, Statistics is a better fit for you.
