Bene Gesserit are a small group of beings with powers and foresight
Jedi are a small group of beings with powers and foresight
The Fremen have a Prophecy that the son of a Bene Gesserit, the Mahti, will come and change Arrakis for the better of all Fremen
Jedi have a Prophecy that the chosen one would bring balance to the force
Paul "Mu'Adib" Atreides is the most powerful Bene Gesserit that the prophecy is talking about
Anakin Skywalker is the most powerful Jedi that the prophecy is talking about
Paul "Mu'Adib" Atreides conquers the universe in the name of the New Empire
Anakin Skywalker, now Darth Vader conquers the universe in the name of the New Empire
Even though he fulfilled the prophecy many considered him evil for the large scale wars and the slaughter of enemies. Even many of the Fremen who prayed for the Mahti, hated and cursed him. They weren't prepared for how quickly he would change their environment and customs
Darth Vader did fulfill the prophecy. During the time of the Republic, the Jedi were a major force and the Sith were all but extinct. Balance means equal or a sense of symmetry. When Darth Vader massacred all the Jedi, he fulfilled the prophecy by leaving only two Jedi and two Sith. Perfect symmetry.
Under MuAdib's rule many think it would be best to draw up a constitution. Mu'Adib denies the request. He considers democracy to be too chaotic, hence becoming the Emperor of the universe.
The universe was a Democratic Republic , until Darth Vader and the Chancellor decimated it and created the Galactic Empire
The prophecy, assumed to be a good thing, resulted in being what many considered a great evil

The answer is that they are symilar, but there are so many variations that even if lucas did copy Dune and rewrite it in to Star Wars he did it in such a way that made it so diverse that makes the book and movies very different from each other.
