XD thanks to me being an antique i am the real aizen (ive been using this name for a long time know) and i never said i wanted an itachi uchiha copy in my ranks, i have a madara (wich is stronger) a gin and a tosen already, hahaha i like that bankai: shonetsujigoku, but is that the name of the zanpakuto or the name of the bankai

and to answer you itachi yes the real aizen would own the real itachi there is no doubt aizen is much faster than sound his strength is one of the higgest shown in bleach and a his energy can kneel someone like grimmjow... so yes aizen would win
