I just read the 6 Dune chronicles, the sequel series (hunters and Sandworms of Dune), and am reading Paul of Dune now before I begin the legends trilogy. Dune is my favorite sci-fi story of all time and the first Dune book is an absolute masterpiece. While reading, I noticed similarities with Star Wars and GoT. Conversely, I remember reading that George Lucas said Dune was an inspiration for his story.
However the other day I saw a trailer for the Foundation show on Apple+ where they said the Issac Asimov books were actually the inspiration for SW. Also, the trailer presented Foundation as a story very similar to Dune. As a Dune loyalist and enthusiast, this was upsetting, as I feel Dune is wildly unique.
I have two questions:
1) Since Dune was written in 1965 and Foundation in 1950, did Frank use Foundation as an inspiration?
2) Since I have never read Foundation, which is better, Foundation or Dune?
