If you want half-assed keyword based completion, you don't need any plugins at all (e.g. ctrl-n in vim). And if you install a proper plugin that uses language servers, you're at the same level of VSCode, which I'm pretty sure is the most used editor by a wide margin. Your rant sounds more like you're more annoyed by "wannabe-vim-hackers" than any actual limitations of the tools.
