Compared to Daulat Ram College and Indraprastha College, Kamala Nehru College is a better option for pursuing an Economics honors degree. It is way better than IP. It is also more reputed than the others. However, you should do your own research on the institutes, by talking to the current students. 

Among these institutes, Daulat Ram Collge has a great Commerce faculty base. The professors are well-experienced and dedicated. They help students with their doubts even after college hours.  It is situated on the north campus. It is a fun place to be. There is always some event going on. Also, Daulat Ram has a great fest called Manjari.  Gargi College and Indraprastha College for Women are also good alternatives. If you clear the required cutoff for all these colleges, your preference order should be Daulat Ram>I.P>Gargi. 

One of my friends studied Commerce at Daulat Ram and it had a fantastic faculty. Here are some things that she considered made it better than the other two. The professors were dedicated and committed to their classes. They were highly experienced as well. The college recently had many positive improvements making it one of the most trendiest colleges. It is at the North Campus which was an advantage in itself. Culturally, Daulat Ram College (DRC) encouraged students to take part in fests, societies, clubs and even go for inter-collegiate competitions. Manjari is the most important college fest of DRC. Indraprastha College is overall a beautiful college with very high education standards. But being a bit isolated from the North Campus, students tend to miss the city life. Gargi more or less provides a similar atmosphere like DRC. Therefore, it is suggested that you opt for DRC or Gargi followed by Indraprastha College.

Your preference order should be Kirori Mal>Ramjas>IP>Daulat Ram.  KMC and Ramjas are both situated at the heart of the north campus. Both of these institutes are also equivalent in terms of the academics and faculty base for Economics Hons. KMC has a slight edge over Ramjas in terms of a better student crowd.  IP College for girls is also a good option for girls with strict and good faculties.  Although Daulat Ram is also situated at the North campus, the faculty base is not that good as compared to the other three colleges. 

There is no clear winner. Both IP College for Women and Gargi College have their advantages. So, you should choose among these two institutes, based on your course of choice and the distance of the institute from your home. For Commer courses, Gargi College is better, while for Arts, it’s IP College. IP is a north-campus college, so it is a bit isolated from the other colleges. The number of societies at both colleges is almost equal.
