> The best programmers I know actually have zero editor loyalty.
Thanks. This comment made me feel like a best programmer.
Jokes aside, I love trying new tools, and it's probably just curiosity, and every tool you try either teaches you something you like, or something you don't. For instance, it's unlikely that I'll ever use an editor that doesn't have a vim-like plugin (for input), but I can't get myself to actually use vim anymore. At the moment I mostly use VSCode, Emacs, or IntelliJ... depending on the language and the support editor's for my workflows (in that language). In emacs, I tend to use the terminal in my editor, whereas in VSCode I'm usually switching between iTerm and VSCode. I sometimes run tasks, builds and debug from IntelliJ, but I'm not sold on the embedded terminal.
I'll have to be honest with myself here though: I often feel that whatever editor I'm using does indeed impact my productivity and that none of them is perfect, and perhaps this is why I'm never happy with any editor in particular. I've never really used a proper IDE other than XCode (maybe emacs counts as one, but I don't think the way I use emacs counts), so I'm always curious when I hear people talk about Visual Studio + ReSharper. I'm not a .Net developer and I don't use Windows, so I'll probably never know.
That being said, my productivity also varies from stack to stack. I'm not as productive in JavaScript as I am in Go or (I would say) Rust, and I think it's just down to the fact that the tooling is great in most editors, as well as outside the editors. I'm not sure I can confidently say that bout JavaScript/Typescript (although much better now than say 5 years back).
