Yamamoto claims he is the most powerful Shinigami ever born, and there hasn't been anything to disprove that.

Individually, I'd say no, but I could see the Royal Guard being able to take on Yamamoto if working in conjunction.

As for Ichibei and his naming power...how would that make him physically or energetically stronger than Yamamoto?
