I'd say my experience matches this. I've written well over 50 KLOC of both Go and Rust in the last few years (I love both), and I don't personally experience a big productivity difference between them. There is one dimension where I feel like Rust makes me more productive though: when writing code that I want to go as fast as possible. I bet there are things that would be more productive in Go, maybe building web applications, but I haven't built any in Rust yet, so it's hard to compare. As a reference point, I feel much more productive in Rust/Go than I do in any unityped language. I suspect the same is true of C, but I've never been a heavy C practitioner. I'll stop here though, because this is all pretty subjective and wishy washy, and it will undoubtedly vary from person to person and be dependent on what kinds of problems you're solving most frequently.
