React (vanilla, Native, and Electron) is the one to beat here, not platform native toolkits. For a toolkit to be world class today it needs to be cross platform across web, Linux, Windows, Mac, iOS, and Android. Companies want to reduce duplicated effort per platform, in order to make frontends faster and/or cheaper. That's the number one feature a toolkit can have.
