I've heard this one before. I still use Mathematica (Home edition). It has curated data and more than just a notebook interface, which it pretty much invented. I use Julia with Pluto, SMath Studio, Frink, and some others for Maths toolbox. I love to play in Mathematica. It is function rich and the documentation is amazing. I usually prototype/research in it. But then again, I drop to BQN/APL/J for some math fun.
