Bun doesn't require special tooling since it uses standard TS and follows the Node conventions. With Deno you need special tooling for eg the weird import system and package manager.

Bun also includes stuff that you'd need a third party dependency with Deno or Node. Eg: database drivers, S3 client, etc.

Finally, Bun overall has better performance and efficiency compared to Deno.

That said, I'm going back to Node after the recent Bun fiascos with their Rust AI re-write.
