Hello Monisha Gupta, According to me Janki devi memorial college is slightly better than Mata Sundri. As the cultural societies and cells are very active in Janki Devi memorial college in comparison to Mata sundri college. Rest is your choice. Best of luck.

Janki Devi Memorial college is a little better than Mata Sundri college for women. You can have similar placements or internships in both the colleges as the placement scenario is not very good. But you can have a good campus and good ambience in Janki Devi Memorial college as compared to the other. 

But whichever college you choose you can perform well to carve a niche for yourself. 

All the very best
