[nim-godot](https://github.com/pragmagic/godot-nim) is excellent. Rock solid in my experience. However, it's mostly unmaintained and it's Godot 3 only, which is at this point is a fairly major issue. It's still working very well for me, but it's hard to look at the shiny new Godot 4 features and not feel a bit envious.
[godot-nim](https://github.com/panno8M/godot-nim) supports Godot 4 and looks very promising, but I haven't tried it yet. I'm hoping to play with it over the holidays.
