the Hekate class is very good, and gets into some gnostic texts at the end. Theres not really much work with angels, maybe a little in some of the PGM stuff, but not much at all. PGM 1 is ok. PGM 2 is less well researched, or at least I noticed inconsistencies and adaptations that seemed incorrect when I looked at some of the source texts. I've noticed a growing cult-like devotion to him and dogmatic adherence to his style that some of his students exhibit that is a little disturbing. If you look at threads in other spaces where they are active and anyone questions the cost of his book or the value of what he offers, they get rabid and defensive. If you point out an alternative interpretation of a spell or something that reveals that some of what he puts out there might not be entirely accurate, it doesn't seem like he's open to considering that or that he appreciates any kind of critique or feedback like that. That's a red flag for me. I'd recommend the Hekate one. The others could be worth it if you have a discerning eye, but if you do your research and explore the PGM on your own, you might come to some different conclusions and approaches and honestly get more out of independent research. Over time I think his style has changed, and I've liked it less and less.
