I'm going to give what I've realized newer folks to Vim think is a scorching hot take: VimL is nice. Theyre the same editor commands you use in your day to day life, even if you're using NeoVim + Lua, just all written out in a file.
That said, using NeoVim + Lua makes it far easier to organize your config, which also makes it easier to write more complex configs. It's like the difference between building a shed around back for your home office vs building a cathedral. Its fine to work in a shed, but once you know you can build a cathedral, you're kinda tempted to just up and do it
At first maybe. But when you get your vim config well honed over time you're good. Plus there's things like pathogen or other frameworks to add plugins and stuff.
