I'll bite.
Even at the most basic level of built in functions/methods (String, Array, Hash) - I found Ruby's to blow Python's out of the water.
https://ruby-doc.org/core-2.5.1/String.html
https://www.w3schools.com/python/python_ref_string.asp
Even Python's choice of naming and syntax to use these basic functions just hasn't been thought through as much as Ruby's implementation. There's a reason it's called the language of Developer happiness.
Ruby's community I've found is more focused on best engineering practices (like testing) than others, which is perhaps why RSpec and MiniTest are fantastic frameworks. The likes of PyTest doesn't even compare to what those two offer.
Plenty of reason above to use Ruby, and we haven't even got to Rails yet.
