I have the same setup in both vim8 and neovim. It's symlinked over from neovim, because I like the xdg ~/.config dir better, keeps things tidier. Basically pathogen, lightline and vim polyglot. I use vim8 most if the time out of habbit. I like Lua better but I understand it has poor handling of strings and I don't know how that fares with and editor extension language.
