I would describe a top notch girl as solidly hashkofik Bais Yaakov girl, willing to support a husband because she sees the chashivus of Torah.
According to the Lakewood Shadchanim, the support needs to be up-front, not just a “working girl”. Working girls have children and eventually get worn out. PHD’s will still take care of the home (and themselves) while the boy sits and learns.
Top notch boys deserve to come home to a clean and calm house, where they can relax before going back to night seder. Not taking care of children because the wife needs a break from her 18 hour workday (between work, commute and children).
