Well, maybe it is just Grimmjows misinterpretation: At the time he made this statement there were no stronger beings with Hollow powers known than the Espadas (and former). But Ichigo obtained Hollow powers on Espada level and beyond. He (or his inner Hollow) used a Cero against Ulquiorra aswell and the Gran Rey Cero is basically just a Cero with more piercing force.
