I don't find ooRexx useful on the PC as it's basically on life support where Python has millions of contributors. Take data validation as an example. There is a first class library https://docs.pydantic.dev/latest/.
Python isn't my favorite language by a large margin. But it is useful so it wins. Same same with Java. Personal preference is secondary to a pragmatic choice.
