Hey,
Both colleges be one of top colleges of du for women as being the north campus colleges. But when one has to make a choice between then you should go for ip college.  Indraprastha college for women will not only provide you with great campus and infrastructure but also with great faculty and crowd. The infrastructure when compared to daulat ram has much better position and also ip has the one of the best campus in du. The faculty is great and the placements cell of ip be always in name as it provides a good number of placements and internships.
Hope this helps.
