I switched to Emacs over two years ago because I was getting too comfortable in VS Code. If VS Code didn’t have the “dodgy” stuff, I would recommend it to everyone without reservation.
Emacs has been a pleasant surprise. The latest versions have introduced Eglot (LSP), EditorConfig and a few other odds and ends that make it very close to being usable with very little configuration. My latest suggestion for getting started is JUST two lines of config, and I think you can scale easily.
I just wish Emacs had started from the outset with more common keybindings- it makes it hard to recommend because you need to make a significant investment. I think it’s worthwhile, but still…
However, due to how it’s evolving lately, I suspect it might become even easier to get started with time. If they rolled in to base Emacs automatic LSP installation, that would be huge, for instance.
I don’t use Nextcloud calendars or address books. But I assume they are included in regular backups.
I pay about 50€ for all absolute overkill Hetzner dedicated server (128gb of RAM).
I live in two different flats in different cities because of personal circumstances.
