Not quite, I distinctively remember Yammy saying he was the strongest espada, and given the fact that he had 2 resurrections I was inclined to believe him. He referred to Ulquiorra and the rest as trash. Ichigo pretty much jumps up from power level to power level without rhyme or reason. In HM, he was easily defeated by Ulquiorra, but was able to keep up him a few (fights?) later? He didn't train or learn a new technique; he fought him the same he fought him before, except this time he wasn't destroyed. Furthermore the fight itself is bullshit because Ichigo shouldn't have turned into a full hollow... and if he did, Hollow Ichigo would be in complete control, not some mindless zombie.
There's also Aizen vs Ichigo. We never did get an explanation as to why Ichigo (who trained for 3 months) could easily overpower aizen at the near peak of his form with that dumb jewel. It's theorized that he gained full power from his hollow form & bankai spirit, but meh that's insubstantial. I've got more issues with Bleach's consistency but I can't be arsed to find them.
