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.
