Hello Dear,

both are good colleges in terms of women facilities.

some key points are :
Ethiraj college - established in 1948. private institution.affiliated to the university of Madras. good hostel facility and canteen are average.

MOP - established in 1992. private institution.affiliated to the University of Madras. good hostel facility and canteen are good.

so according to me, Ethiraj is good in terms of MBA in Chennai but MOP also a good choice.MOP is the newest and ethiraj is the oldest and have a name.

good luck
