I'm not investing in Genesis 9 right now,  mainy because Gen8 had so many great characters that my library has all the variety it needs to tell my stories.

I'm also using 4.16 primarily for rendering and runs well on my system.  I do have 4.21 installed for testing on another computer,  but that's it.

I think the whole market is going through transformations right now,  facing challenges with everything from introduction of AI to the slowing down of the economy.
