For the *dimensions* of *gravitational* potential we are actually *both* 
correct because what I stated is actually not contrary, but equivalent to 
what you indicated:

  [U] = [G] × [m] [M]∕[R] = 1 m³∕(kg × s²) × kg²∕m = 1 kg m²∕s²

  [V] = [U]∕[m] = 1 kg m²∕(s² kg) = 1 m²∕s² = [length]²∕[time]² = [speed]²

<https://en.wikipedia.org/wiki/Gravitational_potential>

However, it is of course only that simple in *Newtonian* mechanics, which 
does not apply to black holes.

Sadly, you are a hopeless case.
