You can add Flutter to this list which is becoming a viable option for desktop UIs. The downside is Dart, but that's not so different from picking Pascal/Delphi just for its UI framework.
I would say the downside is Google, because they may just kill Flutter and/or Dart even if they get popular. I just can't make myself hitch anything important to Google's tech anymore.
I do think Dart itself is a fine language, though.
