Honestly I think, at least to the Zig community, But isn't the biggest name we'd think of. There's been some philosophical friction between the Zig project and Bun (Zig is pretty anti-AI and favor methodical thinking through of problems, while Bun is more move fast and break things). I think TigerBeetle is a better representation of what Zig can do. TigerBeetle is fuzzed within an inch of its life, and is absolutely rock solid. The people who work on it are brilliant programmers who care a lot about correctness. They find that Zig lets them express their ideas succinctly, while still giving them the needed power.

When I read about Bun, I get the sense that Jarron has different priorities, mainly moving quickly. Bun also implements a lot of userspace APIs, since the core engine is JavaScriptCore which is written in C++. I think Rust really shines in applications programming, so I guess it makes sense that Rust has lined up with Jarron's needs. I'd be interested to see what JavaScriptCore would look like in Zig versus Rust, I think Zig might have an edge in the core interpreter and JIT.
