I think you mean, how is this better than https://http.cat/

I've been a fan of https://httpstat.us/ for a while now. Pretty much the same thing only you can also ask for a specific response time, which can be useful for testing timeouts.

Well that site only shows me one status code. It's a 522 generated by cloudflare because they can't contact the host.
