Neither Naruto or Momo are Uni+, and even if we accept they are, Rei-o can easily be scaled to a comparable level or even higher due to being the creator of the Bleach cosmos.
The Almighty renders Rei-o immune to Shibai's haxxes , + gives him future sight + Fate manip.
Visionary can do the same thing omnipotence does (Reality warping)
Anti-thesis and the Balance both counter reflection Shinjutsu.
Not even gonna mention his other haxxes which would include all the Quincy schrifts such as the X-axis,Deathdealing,compulsory, miracle etc.
Tl;dr; Rei-o has everything Shibai has, and much, much more.
