Actually what is said is that when using the mask while in bankai he uses the getsuga tensho as his most powerful attack, with Ulquiorra comparing it to his Cero Oscaras, which is his most powerful attack. It was never said to be a cero nor was it compared to one specifically in power. Whether Kugo actually used a Cero is suspect but more importantly if ichigo stops an attack that really doenst have anything to do with the conversation. In any case the mask may not play a role anymore cause it was a reflection of Ichigo's detachment of his powers. He went from being Quincy controlled Shinigami powers w/ Partial Hollow Powers to learning the truth and Integration of his Shinigami/hollow powers and Quincy Powers, while accepting this.
