No doubt. But we don’t know what that advantage was. You could assume it was for performance related reasons. But maybe they wanted cross-platform compatibility, something WASM allows far more than JS. Or maybe they hired a load of developers experienced in making a graphic design tool rather than making a webapp and decided to use WASM to provide those developers with a more familiar environment.

Anyway, without knowing any of this it’s very difficult to say “Figma did it so we should too”.
