I love it. I have 40 files open in it right now - most of them .c source files with LSP and Treesitter running and it uses 250MB of RAM. Everything works instantly, Telescope is imo the new standard for file navigation (and navigation in general: grep, symbols even neovim shortcuts). Git integration is fantastic as well.

I have spent some time configuring it and probably will spend more when I start including more languages but imo it's worth it. You can configure everything but you can also find very nice defaults by running Kickstarter (or some heavier neovim "distro").

Microsoft has done great work with LSPs - I can now get great navigation/autocompletion/formatting/inline errors/warning combined with neovim navigation, light weight and fantastic tools/extensions.

One thing I haven't integrated yet is a debugger (gdb from the terminal is good enough for me), maybe that's something people are missing in neovim?
