Most of the time, I suppose. Watching someone try to write java in vim (or generally, without an IDE) gives me anxiety though, even with a language server :)
Meh, it's fine. In general, I find that vim in more productive most of the time (now I have a language server, before, wouldn't ever consider it!)
The fluid and consistent (java is only a portion of what I write at work) editing experience is mostly more valuable to me than the slightly better autocompletion.
I keep intellij installed, but it only open it if I want to do a fancy mechanical refactor, like extract an interface from an existing class. Smaller niceties like creating a local variable from an expression are only a handful of keystrokes just feel like naturally describing what I want (lexically, rather than semantically, I'll admit) in vim anyway.
That's perfectly doable. I routinely navigate / extend / debug / refactor a 600 KLOC Java codebase with nvim + ctags + ripgrep and will have the job done well before the language server has even completed digging through those 600 KLOC.
