.NET (Core) was inferior to any IDE (even Xamarin ones) last time I tried it (~6 months back). IntelliJ Rider has been quite an amazing discovery in this regard - I prefer it to Visual Studio.
And then there are things like mobile development which VS Code has realistically no chance of touching.
Any language I can think of other than TypeScript - VSCode just cannot come close to IntelliJ support. I would pay for the ability to have a desktop machine on which I could SSH develop from say a Windows tablet/2in1 with integrated 4G and hardware powerful enough to run the client editor + productivity apps and has portability + battery life (say some intel low power series + 8GB ram)
WebStorm seems to understand Microsoft's TS better than the VS Code Plugin. Complex refactors actually work.
I don't trust any refactoring tool to do cross file refactoring correctly in JS/TypeScript and the code navigation stuff in VSCode has been rock solid for me - I don't really miss anything and it's a much faster environment to work in - if I just had to do JS/TS development I could switch without any issues.
