I love Go for quick and dirty CLI apps. They are a bit bigger than the C app but so much friendlier to develop on. Rust is better for more complex processing, but it is also less straightforward (at least for me).
I say this as a Rust fan and a (sometimes overzealous) promoter; it's just easier to wrap your head around programming in Go. They have made it so easy and enjoyable. It really is a pleasure for quick concepts to table, so to speak.
