When was the last time Mayuri won a fight because of his strength? I think never. He lost to Uryu, and he defeated Szayel with his wits and superior beliefs about what science is and is not. Mayuri isn't on the same level as Kyoraku or Urahara.

As for Soifon, I disagree. Weak, because she couldn't defeat Barragan? Not her fault. I say she'd be able to take down Starrk or Harribel rather soundly.
