This is why I switched to Helix. The configuration is practically non-existent, and it has default configs for all the language servers I could ever want to interact with. I just put the language server binary in my path and I'm ready to go with autocomplete and all the other features.
Helix is cool, but it doesn't have Vim keybinds, which is unfortunate. I find its own system to be a little worse than Vim's (see my other comment about it in this thread).
I've also switched to Helix recently and I get the feeling that is not emphasized enough how much it is about having default integrations for modern standards like LSP, Tree-sitter, and DAP. It's amazing how much functionality you get with just that and not having any plugins or complex configuration.
I actually dread the day Helix eventually gets the WebAssembly plugins system that's been floated around. The current Helix culture of "you get a Kakoune-like editor that can do three categories of "bonus" things, and NOTHING ELSE" encourages a more manageable pace of development (and maybe more importantly: slower updates for those of us exhausted of software churn breaking our stacks constantly), and discourages feature creep/bloat. I love where Helix is at currently. After some tinkering and adjusting a few keybinds, and after a few releases for them to fix various bugs I'd been dealing with, it's quickly become my new favorite editor, and has nearly fully replaced NeoVim. Hats off to Helix.
I couldn't agree more with this! I actively don't want plugins for Helix either - as tempting as it sounds. Nvim is already a create plugin based modal editor with a rich ecosystem, so Helix's no-config philosophy is kinda it's whole selling point.
