both actors provided the same kind of grunts, there's no real change in there because it feels like the same portrayal of the character as opposed to Daisy from quiet to obnoxious , Luigi from high pitched to manly to scared or Rosalina from womanly and serious to more upbeat.
Also let's not count Sunshine's voice acting because besides that , it just the same material aka monster like sounds.
And again, im not negating the fact that there's some level of difference but to say that it's the same level as the characters above is just not real, let's be honest now.
