Why are you so obsessed with this subjectiveness? I'm just saying that speed and vim-like editing where not a selling point. Because you can already have those in VSCode with neovim backing it up. Not to mention you could've already have speed and vim-like editing via projects like VimR (tens of them out there).

You are contradicting yourself here.
[^1]: "(neo)vim plugin installation still isn't as easy to work with as a one click package / language server install like in VSCode."
Regarding the plugin support, there is no contradiction. Rather than the words "one click" however, which brings to mind a GUI, I should have said Neovim has a more annoying plugin story (through packer which has a lot of configuration) than VSCode or OniVim, yet it is not the GUI that makes it so. If I could write in init.nvim "Plug TypeScript" just as in VSCode I could click "install" on the TypeScript extension, those are both equivalent to me, even as the latter is GUI based while for former is terminal based.
Speak for yourself, those are why I supported OniVim. The GUI was not what was important to me, it was the ability to install extensions easily, have vim keybindings, and most importantly, be able to handle the very large files I often work with (due to being written in OCaml), where VSCode hangs.
