Obviously depends on the kind of projects you're working on but in our experience we've been more productive in Rust compared to when we've built large systems in Python, Go, C and C++.
This is with regards to long-term productivity however. Generally it shows up in building things that work right the first time around, being able to refactor confidently, etc. Personally I still find myself faster in Go or Python if I have to throw a short-term project together very quickly but other members of the team still profess to being more efficient with Rust for these types of projects too.
