I think it’s merely a design preference. But I preferred the used universe of Star Wars 1977 over the bright and clean cgi esthetic of the prequels. It lent a sense of authenticity and realism that the prequels lacked. And that also the sequel trilogy lacked.

The dinged up and dirty and dingy look of things. Landspeeders, the Millennium Falcon. X-Wings of the rebel alliance. Lightsaber hilts etc, blasters. Kenobi’s Robes. The detail work on Threepio and Artoo. And on Vader’s suit and all its parts and pieces including the cape.

And how the Rebels were much more utilitarian. the Empire more clean and antiseptic and austere in design. How the rebels could just be farmers or privateers or whatever port of call they hailed from. Some of them might even be criminals like Han Solo. Or people out on the fringe. Luke being a former moisture farmer and all of that. Kenobi being able to pass as a Tatooine local wearing the garb of a farmer. Of course, they made those Jedi Robes.

I think each world and culture should have varied more in the prequels. You would only get bright and Shiny on Coruscant but not on the lower levels. the Jedi being at the height of their arrogance, I wouldn’t have changed much about how they looked in the prequels. except maybe different colored lightsabers of various colors and different robes not just the Tatooine garb.
