In what ways is it inferior? Neither Ruby or Python are 'fast', so if that is one of your qualifiers you've already made a suboptimal choice.

As for a bigger community, what does that serve? The large python community adds misdirection and more voices to a language that lacks some basic features still. Async/sync code models are still being finalized whereas Ruby has been stable in this regard for 10+ years. Same with tooling - the Ruby side is more consistent and stable: Sidekiq for background jobs (Celery is barely coming to maturity), Bundler for dependencies (pip? poetry? uv?). Mature auth + other frameworks like Devise.

Having worked in both languages professionally, I strongly disagree with your take.
