For me the value in Zig is its simplicity as a language (in a way similar to go's simplicity) and the explicit and very fine grained control over memory allocation. On top of that, I really appreciate tagged unions and error handling. It adds enough value on top of something like C to make it worth for me.
Still wherever I need absolute code correctness and production grade quality, I use Rust, my favourite language, at the expense of more code and spending more time doing it "the right way".
