I wish you had tried C# with WinForms which is still has the best GUI development tooling in Visual Studio.
They didn’t need to because they already had WinForms as a baseline experience for Windows UIs.
It's a great successor to IMHO one of the other all time best RAD environments, Visual Basic. (Though I've head Pascal had some really nice out-of-the-box tools for GUI work)
Anyway, I think this generation is missing out on the experience of building in a real RAD environment. I'm more on the backend, but from what I see the pinnacle is fast hot reload, which pales in comparison to what could be.
