With Neovim 0.5 you'll get native SLP and treesitter support. And it has first class Lua support, which is a huge improvement over vimscript for plugin writers and if you do larger configs yourself. These are by no means must haves, and there are workable alternatives, but IMO they're nice improvements that warrant the small switching overhead.
