I don't know the comparison between them. But your question is also loaded (intentionally or maybe not). Why I say loaded? How you formulated includes the hidden assumption that Python is more advanced or faster. Thus it is not an open question. This may not be your intention, so I am sorry if I am interpreting it in the wrong way.

I got triggered by this because a lot of people put a lot of effort into making this release happen. Don't take away their "wind" by asking veiled questions that hint that other languages are good, especially as this submission is just an announcement and does not make any comparision between Ruby and other languages.

It is ok if you like Python more than Ruby. There is a place for everyone, and I wish people would adopt the mindset of "growing a pie" and not act like every release of any other language is a direct hit to their own choice.

About speed, I would say this:

- if you are creating a project with speed as the primary business value, then yes, don't choose Ruby. Choose C or Crystal

- if your project is a web app, then it does not matter if you choose Python or Ruby

- rarely a project that has speed a core business value dies out because it is slow. So from a business perspective, the criterium of speed is irrelevant.

You can still use Ruby if you have a need for speed. Try JRuby, TruffleRuby, or mruby depending on the application. But be sure that MRI isn't fast enough. MRI will improve faster than any of the others.
