I don’t want to consider either the Sequels or the other films created under the Disney direction of Lucasfilm, except Rogue One. So my ranking will include only the 6 original films created by George Lucas and Rogue One. My ranking will have a descending order, and it will go from the movie I like the most to the one I like the least.

Revenge of the Sith
The Empire Strikes Back
Attack of the Clones
Rogue One
The Phantom Menace
Return of the Jedi
A New Hope

I think the Prequel Trilogy and the Original Trilogy are on the same level, I don’t like one more than the other. But, individually, I like the Prequel Trilogy films more than the Original Trilogy ones, mainly because the Original Trilogy films have aged rather badly in my opinion. Besides, I disagree with many of the criticisms of the Prequels.
