Which to pick

Downloads tell you what is common, not what fits. Each crate's own description above says what it is for; when the jobs differ, pick by the job.
When both fit, prefer the one more crates depend on (textwrap, 750 dependents): more eyes, more answered questions, and you may already have it in your tree.
