Having to know some people studying in both JMC and KMC, I might be able to share some of the details about them. Here are some pros and cons about each college, which will help you differentiate between them.

Pros

Kirori Mal College

• Being a north campus, it is considered to be appealing to the students.
• The placements here are excellent.
• Transportation and Connectivity is excellent.
• There are no strict rules about attendance.
• The faculty members are helpful and cooperative.
• Students keep themselves engaged with societies/clubs activities. 

Jesus and Mary College

• This is a lovely campus, located at Chanakyapuri, Delhi’s most upscale, clean, and safe neighborhood.
• It is close to Satyaniketan, Sarojini Nagar Market, Connaught Place, Greater Kailash, South Ex, and other fantastic hangouts.
• They have a competitive student crowd.
• They have excellent societies.
• The placements are really good.

Cons

Kirori Mal College

• The infrastructure is poor and not well maintained.
• The crowd is a little dull and there isn’t much competition among the students.

Jesus and Mary College

• Attendance and study are strictly enforced. 
• Connectivity is poor. Metro stations are a long distance from the campus. Autos, on the other hand, are accessible on a 20-per-share basis.
• There are fewer hangout locations on South Campus than on North Campus. 
• Teachers are strict and expect proper discipline.

Therefore, these are some of the facts about the college. The only thing is Kirori Mal is a co-education college, whereas Jesus Mary College is only for girls. See what suits your requirements and choose accordingly.
