Vim + TeX Live on Gentoo

Overleaf, because I don't have to download an application.

VS Code with the LaTeX workshop plugin. Works like a charm. You need to have LaTeX installed in your system

I myself use TeXStudio with a texlive-full install. I may switch to something else, but currently it is a convenient setup.

Neovim with vimtex and texlab language server. Learning nvim takes some time, but I made preconfig, which allows to start a bit easier

MiKTeX, because it's the first one I stumbled upon in high school and I don't use LaTeX enough to be bothered to optimize my choice of editor.

TeXStudio for the convenience of compiling and managing multi-file projects; (neo)vim for serious work with the tex files.

emacs

Nvim. autopair.nvim let's you autoclose "begin[]" macros. Luasnip let's you create custom snippets for every macro you use. I also use Emmet LSP for inline svg.

Usually Neovim and :!tectonic main.tex, nothing fancy. For preview ideally Zathura or Preview on Mac.

Also VSCode is quite usable, since there are some pdf preview plugins.
