Have you already settled this, or is it still open?

Asking because I maintain a tool that builds this comparison from live registry figures — weekly downloads, version, license, bundle size, each with a collection date. If it's still open I'll run it for your case and post it here today.

Not trying to push anything: it's more useful to me to find out whether this actually helps anyone.
