It's true that the one who counts the votes matters and this doesn't change with mail voting / in-person voting The one advantage of physical voting I can think of is the ability to just be close to voting station on voting day, counting people who go in there, asking people (who are willing to share) for whom did they vote. This allows to independently check if fraud exists.
