I'll sit next to 1, and I'll spend the entire flight talking to him about my .NET setup on Windows and how to date Visual Studio is still the best IDE available for any mainstream programming language.
I'd consider vscode to still be a text editor, although I do really like using it for TypeScript. For me, VS still takes the crown because it's just so good at debugging and evaluating C#. It's hard for anyone to compete since Microsoft largely owns (yes, I know the .NET Foundation is responsible for .NET) the whole ecosystem.
Vanilla vscode is not an IDE, true. But that's a moot point as you can load that shit up with a bajillion extensions and turn it into what's basically a proper IDE.
It has seamless integration with the language and framework, and to date (outside of TypeScript support in vscode) I'm yet to use anything that comes close to the level of control in debugging. IntelliJ shits the bed at even basic Gradle builds.
I was so excited for Rider, especially since I do like some of the features of other JetBrains IDE's, but I've found it just too unreliable when it comes to build support, and despite years of dominance in tooling from the ReSharper days VS intellisense is just much nicer. It's very close though, and IMO Rider is nicer to use for C# than IntelliJ or PyCharm are for their respective languages.
