I'm not an IntelliJ user, I mainly use PyCharm, but at first I listened with some skepticism, wondering if there was anything else to learn, but there were some parts that I had never heard of before. I've watched the JetBrains PyCharm tutorial quite a few times, but there was some content that wasn't in there, so it was good. I think even those who have used it a little bit would benefit from listening to it once.
