Let's put this in context. At the moment the main thing that's happened is Xamarin Studio got rebranded as Visual Studio for Mac. If you look up the features of Xamarin Studio you'll have your answer, at least based on the current features.

You can reuse a lot via vs/xs if you like C#. There's support for UWP, iOS and Android, as well as libraries for GTk and Mac.

I'd be more inclined to use react and Redux with electron. With Cordova to bridge to mobile.

Really do like VS Code.

Just my two cents.
