Ask HN: Anyone used newer (2019-2020) Xamarin.Forms for cross platform desktop?

What the title says. We are looking at desktop app development that is cross platform but as native as possible and looking at Xamarin.Forms, Qt, and React Native.

We're pretty much down to Xamarin and React Native, with the latter looking decent due to Microsoft's recent efforts on react native for desktop and even for Mac desktop. Qt isn't totally out but its not truly native controls and if we are going to do the not truly native route we might as well go with some HTML5/CSS UI option.
