Byakuya Kuchiki takes this.....
No one with in the naruto Verse can match those of bleach, EVEN if they where in the same universe.
Everyone in bleach moves as fast as FTG in naruto, however it is completely different. Unlike FTG flash step (The method bleach characters use) does not require seals, it is the body of the character/ the limbs that work this technique. In other words the bleach character (Which in this case is Byakuya) can move anywhere, anytime, without any effort, nearly the speed of light.
Even if we were to slow him down, Byakuya knows Kido, which is spells (Basically) that can create almost anything (in multiple elements) and quantities. He is also very good at using Kido, as shown in the anime/manga. It takes him no time at all and no effort.
This is all without him even using his soul reaper. In its first state (Not bankai) it can not be seen or heard, yet with enough power and speed to cut throguh metal with relative ease. IF he uses his Bankai, you are talking about millions, upon millions of petals so sharp and deadly they would cut your skin with no effort what so ever. this can surround his opponents and keeps cutting till there is nothing left.
(Even if Amaterasu is used, it want do anything at all) the petals that Byakuya are metal like objects made of Rietsu/chakra
