Toshiro and Sui Feng are weak. Weakest captains along with Komamura.

Sui Feng hasn't won a major fight in ages. She was outclassed by Yoruichi, who is a rather weak Shinigami herself (When Yammy is able to nearly kill you, then you're doing something wrong), she was punked by Barragan, and BG9 just took a shot from her and wasn't even badly wounded. She's a wally and a pushover who talks big and then gets her ass beat.

Same with Toshiro. He struggles against everyone. He only beat Hallibel because Ice is the perfect counter to Water. If he faced Ulquiorra or Nnoitra, I think he would have lost.

Strong captains are the likes of Shunsui, Ukitake, Kenpachi, Byakuya, and Mayuri.
