I guess, Delhi University is surely better because there are very few seats and high competition. So, it has more value and the faculty of DU is amazing as per my experience. Rest, it's surely your choice.

It good percentage you can get admission easily as mathematics matter a lot.

Depends on your career goals, career aptitude, job profile and industry sector that you wish to work in future. If you want to go with MBA after deep knowledge of economics, can learn management programme much better especially in terms of how external environment impacts the businesses and overall impact of economy on industry sectors etc. MBA in finance management would be better option for economics background student.

According to me, people holding rank 43 also not getting admission in North campus, because there are fewer seats. It will depend upon your rank but it has to be in top 40 atleast to get north campus.
