Download counts don't mean very much here as I'm fairly sure both crates are common transitive dependencies. Or in other words, millions of programmers aren't individually choosing Anyhow or Thiserror on a monthly basis -- they're just dependencies of other rust crates or apps.

And agreeing with the other reply, nobody jumps up and down with joy when choosing an error handling crate. You pick the right poison for the job and try not to shed a tear for code beauty as you add in error handling.
