I assume you meant AtereS and not AtereT. These are two different seminaries; Ateres is Bais Yaakov and relatively strict (compared to non Bais Yaakovs), and Ateret is completely not Bais Yaakov- the girls who apply there also apply to Sharfmans etc.
Darchei Binah has great, world renowned teachers, and the girls can get close to them. The girls that go are a mix, there are many really solid, growth oriented girls, and there are some that will party in ben yehuda–but you have that in every seminary, even bais yaakovs.
the teachers are all encouraging, and really help the girls grow, both in Torah and middos. their philosphy, like zk said, is guiding rather than strict; they dont force things down your throat, but after spending a year with inspiring teachers who have all accomplished a tremendous amount, the girls come out with a new perspective on life.
darchei binah girls are all sweet, friendly, Real girls (not hiding anything, or pretending to be someone they’re not), who come out of seminary being very comfortable with who they are (great, smart bnos yisroel!)
any other questions??
