Search for pointer exceptions or core dumps on Bun's GitHub issues and you'll see why people (should) use Deno over Bun, if only because Rust is a way more safe language than Zig.

Don't make a false equivalence, how many times does one get a panic from Deno versus a segmentation fault in Bun? It's not a similar number, and it's simply wrong to say that both are just as unsafe when that's plainly untrue.
Anecodtally? Zero segfaults with bun since I started using it back in beta.
The only time I got a segfault in Bun is when I used bun:ffi to wrap glfw and wgpu-native so I can threejs on the desktop. Ironically, the segfault was in wgpu. Which is Rust. But to be fair it was because the glfw surface had dirty flags for OpenGL and didn’t have the Vulkan extensions. So anyone would have faulted.

There are degrees to this though. A panic + unwind in Rust is clean and _safe_, thus preferable to segfaults.
Java and Go are another similar example. Only in the latter can races on multi-word data structures lead to "arbitrary memory corruption" [1]. Even in those GC languages there's degrees to memory safety.
I haven't verified this, but I would be willing to bet that most of Bun's issues here have more to do with interfacing with JavaScriptCore through the C FFI than Zig itself. this is as much a problem in Rust as it is in Zig. in fact, it has been argued that writing unsafe Zig is safer than writing unsafe Rust: https://zackoverflow.dev/writing/unsafe-rust-vs-zig/
As someone who has researched the internals of Deno and Bun, your unverified vibe thoughts are flat out wrong. Bun is newer and buggier and that's just the way things go sometimes. You'll get over it.
This is a non sequitur. Both Rust and Zig and any other language has the ability to end in an exception state. Whether it be kernel exception, pointer exception, or Rust's panic! - these things exist.
The reason why you see so many GitHub issues about it is because that's where the development is. Deno is great. Bun is great. These two things can both be great and we don't have to choose sides. Deno has it's use case. Bun has it's. Deno want's to be secure and require permissions. Bun just wants to make clean, simple, projects. This fight between Rust vs The World is getting old. Rust isn't any "safer" when Deno can panic too.
