I love Matplotlib, but I have basically totally restyled it. I really don't like the default styling. Other than that, it is so much nicer to use than Mathematica's plotting tools...
It's very much one for journals. Here is one from my first paper https://ibb.co/373QMfV. Actually here I think the one on the left is matplotlib and the one on the right is Mathematica... I basically like a bold box and serif fonts
