Re: Byakuya vs Urahara
It should be quite obvious that Urahara would win.

Urahara is the smartest person in the entire Bleach manga. Just by watching Yammy fire his Bala he was able to learn all about it and completely negate it. Even if he just has his Shikai, just by his observations alone he could probably deduce Byakuya's safe zone and exploit it.
Not all Captains are (give or take) the same level. Obviously someone like Hitsugaya isn't on the same level as Yamamoto. Hence, there are different tiers of Captains.
More or less, the tiers go something along the lines of:
-Yamamoto, Unohana, Kyoraku, and Ukitake
-3 Vizard Captains
-Hitsugaya, Byakuya, Kenpachi
Both Byakuya and Urahara are strong, but they're on different levels. Urahara is somewhere around the Veteran's or Vizard's caliber.
