In my experience of using LunarVim (which is also a preconfigured neovim). It is incredibly unstable. Plugins often don't work well with each other. Keybindings overlap. You do it with the hope of having fewer things to configure but what ends up happening is you create more config to disable slow default plugins, or add workarounds to existing ones. Updating neovim or lunarvim always breaks my config. These things aren't the least bit backward compatible.

I'm slowly switching to helix, and this time around will be forcing myself to use the defaults, and not adding a single line of config.
