Languages I use most are Rust and Ruby. I find the type system not frustrating, but challenging, on occasion. But only when I'm trying to write a library with a very convenient, flexible API. Its probably easier to write the first draft of this sort of library in Ruby, but in my experience what the library does under edge cases and bugs is often super unpredictable. Not so much in Rust. I haven't had these frustrations in application code in Rust.
