I don’t use it as much because my day-to-day is RStudio and Libre Office, but whenever I edit .nix files, I do it with Neovim. What convinced me was the internet’s lauding of Vim and reading about Lua and other quality of life improvements in Neovim. What convinced me was how easy it is to install and use for my minimal use case.

I don’t think I had an evaluation period beyond using interactive Vim tutorials until I felt comfortable with it.
