Have any of you found Kindle unlimited worth it for science fiction?

In the last few months I've read:

• Project Hail Mary, Weir
• Fall, Stephenson
• The Ocean at the End of the Lane, Gaiman
• The Ultimate Earth, Williamson
• The first four Discworld books, Pratchett
• Seven Views of Olduvai Gorge, Resnick
• A Memory Called Empire, Martine
• A Desolation Called Peace, Martine
• The first five Murderbot Diaries books, Wells
• The Imperial Radch trilogy, Leckie
• Annihilation, Vandermeer
• The Kingston Cycle trilogy, Polk

For comparison, I think I read two or three books last year. It's starting to be a non-trivial amount of money, even though they've all been the ebook versions, which are generally a little cheaper. Has anyone who reads a lot of SF found Kindle Unlimited to be worth the price?
