I feel very strange hating Windows, so I use Linux, but loving VS Code, so I use that on Linux. I feel like a hypocrite or something.
But the integration with platformio, github copilot, and all the plugins and customization are just too nice. It's a one-stop shop for everything dev-related. It's the only thing I need to run when programming along with a web browser for research.
Some extensions don’t work but many do, you just have to download the extension files from the marketplace website and tell VCCodium to install the extensions from those files.
VSCode is pretty good, but honestly most of these advanced text editors are more or less interchangeable to me, especially with LSP and DAP making language servers and debugger integration editor-independent. I don't really feel strongly about any of them, in spite of the fact that as a comp sci student it's the type of software I spend the most time using. I personally use Kate the most, since it's lighter and integrates better with KDE. On my Steam Deck I use VSCodium for quick edits, because it works better in gaming mode. It's basically what (Ungoogled) Chromium is to Chrome, but for VSCode. For exams at school I use plain old VSCode since obviously I can't install Kate or VSCodium in exam sessions. The experience is all things considered pretty similar for all of these. I guess there just aren't a billion ways to design a powerful text editor with built-in debugger, terminal, file manager and kitchen sink. We've gotten the formula down by now.
I feel pretty much the same way about web browsers. On desktop at least, they're all nearly functionally identical, just that some of them have built-in functionality you have to use extensions to get in others. On mobile Firefox all the way of course, because it's the only one with extensions.
Use whatever you like :) I tried VSCode at work for a few months but it felt quite lacking when working with larger C++ projects. Switched to CLion instead and it felt like it was faster, understood C++ much better, and made it easier to work in multiple files simultaneously. But I could see myseslf using VSCode for some small hobby project, especially if it's C#
