For me, I’ve recently started using Emacs solely due to wanting to try out rust-analyzer¹ (not touching Visual Studio Code since it uses Electron), and I’m really enjoying how insanely customizable Emacs is! The ecosystem around Emacs looks great too, with quite a few packages I´m interested in trying (like Magit²).
