Seriously, there's no benefit to sticking with one environment. The right tool for the job. If you're doing Java for instance, no version of vim or emacs comes close to the functionality of the popular IDEs. With vi perhaps you can type more efficiently. With a good IDE, you can develop far more efficiently. For modifying bash scripts on remote machines, vim all the way.
I could agree with you a few years ago but since LSP and Tree-sitter the tables have basically turned, I'm pretty confident you can get _more_ IDE-type features in Neovim (albeit with some amount of effort, no doubt). But, again, you can tailor that exactly to your liking.
