Agreed that Great Courses has a sweet spot... they bring in great professors who are particularly engaging and good at teaching. So, much more engaging than Coursera on average but still a high level of expertise. For a tough technical subject, the lack of exercises makes GC a poor fit, but for high-quality "edutainment," I think it's a perfect balance. (I particularly liked this class on the Etruscans https://www.thegreatcourses.com/courses/the-mysterious-etruscans.html https://www.thegreatcourses.com/courses/the-mysterious-etrus...) If an author/artist/celebrity you particularly love is on MasterClass, it may still be worthwhile to pay for access to their bit. But you learn much less. I took the Annie Leibovitz photography class and absolutely enjoyed it. I still think about a few things she said. But I don't think it improved my photo portraiture skills at all. If anything, it sort of demoralized me to see the incredible level of input required for portraiture at her level.
