That's not quite what I wrote. There is a difference between the two performances: Holliday's Tony Awards performance presents the *entire scene*, in costume, with an approximation of the staging seen in the show. Riley's Olivier Awards performance is essentially a concert performance, presented without context. In terms of *acting*, that gives Holliday a significant advantage.
As for the critics and voters being *wrong* - when you've seen the entire performance, you can make an informed judgment. You don't have any basis to do that off the back of a four-minute segment on a badly-staged awards show.
