Hum, think about it this way: Bottom captain-level: Mayuri, Komamura, Soi-Fong, Tosen(before his Hollowfication), Rōjūrō and Love. Middle captain-level: Shinji, Byakuya, Toshiro, Jushiro(due to his illness) Superior captain-level: Kyoraku, Aizen, Kisuke, Yamamoto, Kenpachi and Ichigo(last two in terms of raw power). Something like that...
