Hey,

Well all these colleges lies in same parameters and hardly have any difference. The faculty offered among these colleges of du for bcom is equally good and have no difference. The only difference that can be made is in the infrastructure and the ranking of the college. Well i would suggest go for sri aurobindo. It has great campus with decent faculty.  The infrastructure is nice when compared to rest of the colleges.

Else whichever you find more compatible and easy to get  go for it.

Hope this helps.
