I’d say yes, watch them. In order to really understand what’s going on in Star Wars and where the Jedi screwed up, we need to see how lazy and comfortable they got in the prequels. Not only that but there are some other messages in there that are worth looking out for. E.g. in Revenge of the Sith when Palpatine gets elected chancellor and declares martial law (I forgot how it goes in the movie) and suspends congress, Padme says: “So that’s how democracy dies with thunderous applause”. There’s a lot more to that than just a quirky line.

The best order to watch them in was suggested by someone on YT, they said 4, 5, (1,) 2, 3 and 6. 1 being optional after ESB. My 2 cents
