See thats where I find issue. With how people rate the Espada. They have a system of rank based on power. Ulquiorra is fourth and regardless of his second resureccion release there is no proof that makes him any more powerful then anyone above him. His only fight was with Ichigo and it proved he was more powerful then regular Ichigo but not his hollow form. Also there is no way to determine Ichigos power in that besides noting that he is more powerful then the 4th Espada. Normal he could barely beat Grimmjow who was 6th. So to say Aizen wouldn't have been able to take him isn't based on fact at all seeing as Aizen is more powerful then all the Espada without any "evolution". Aizen has stated or shown Yamamoto, Urahara, Yoruichi and Isshin would have taken him out if he was normal. So the using the bases that Aizen had to be more powerful for a form we dont know Ichigo can control, whether he will use it again or how powerful it truly is.
