I downvoted it because I thought it was a bot response. Did not realize you were referring to cli-printing-press. The main difference is that printing press caches a local copy of data heavy sites like Discord channels, ESPN, etc. and creates a CLI for that API.

aclif produces a single CLI with a unified grammar for all APIs, plus support for canonical names (fed by external semantic data layers) and unified auth. It targets enterprise SaaS APIs.
