The selling point is that it's a solid editor with zero config I can use in the terminal for those "in between" tasks where it's not really worth pulling it up in an IDE but worth having some syntax highlighting and LSP support. Think like, I need to make a quick change to a python script in some far flung directory. In/out in less than a minute.
Just the fact that you're asking what my package set was is a turnoff for me. There shouldn't be a package set. It should just work. In VS Code when I need the editor to have additional features I just click the button, pick the extension with the highest number of installs, and 99% of the time it immediately does what I want. In vim you play this whole game where you google for it, gather opinions on the "best" plugin for that task, read the README, "just simply add these lines to your lua config", figure out why the keybind is conflicting with your existing keybind setup, etc etc. Goodbye afternoon!
I've tried lunarvim, astrovim, etc etc. Those work great! Until you actually do want to change something. Now you're back in config hell, and even worse, because you didn't even design this hell yourself, it's someone else's hell.
