I don't have much experience with Rust besides just messing around, so in my case I picked something I know. Also it is a language I personally do not want to really go too deep into until I have a valid use case for it.

For most of my needs, Go offers an excellent ratio of developer experience, features, and performance.

I wouldn't say any language is superior or inferior - they all have a valid use case that makes sense. For me personally, I prefer to validate against the ratio I mentioned above.

That being said, Go concurrency is quite simple. It works well and offers great performance.
