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.

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

TexStudio, the multi view and jump to source/output is great on big projects. Zotero macro is very helpful. Compile/clean buttons that also work on multi file projects are huge time savers.

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.
