True, but I'd still say Jidanbô and Ichigo are on totally different levels. Jidanbô is physically huge and strong, likely overpowering any "normal" normal-sized person, maybe even low-seated and unseated Shinigami. But captain to likely 5th seat level officers, at least in the case of Yumichika (who seem to be at lieutenant level anyway) can probably take him out, although not without various degree of effort.

It's like comparing Ichigo's first Bankai to other Bankais. His displayed all of his power at the time, compressed into a small "regular size" blade, greatly increasing his speed and attack power.
