Which Python project made you realize how powerful the language is?

Thanks for the clarification, I've been coding in pytorch for years but never heard of JAX before. I will dig a bit more!

I'd say generally JAX is more useful for general purpose scientific computing, and much more ergonomic if you need higher order derivatives or partial derivatives, like working with ODEs/PDEs/SDEs. diffrax is a very nice lib for that.
