Curse of Hatred wrote: Sasuke held his own against Ay only through Susanoo and Blaze Release. Shisui would be a lot faster than Sasuke, but I would say that reaction speed is more important in this fight. Shisui's Susanoo has only been in a game so until it appears in other media it isn't considered canon. Shisui's Susanoo is shown in UNSR OVA aside from the game itself, so it's at least anime only.
