I would recommend Julia. I switched to Julia from Python because (IMO) it's much faster and has better libraries.

For example, when I made videos with Python, I would have to save images and then convert to video with ffmpeg. But Julia has a library to generate videos on the fly without saving images. This is massively faster. They might have a library like this for Python now, but I'm not going back.

I don't want to post any of my work because of anonymity, but it's mostly animations of fractals, dynamic systems, etc.
