It’s really hard to compare the two. They’re so radically different, created in different eras, different formats, different motivations (well except for money, that’s a timeless motivation). As an experience, the Prequels are better. The Kenobi show is just kind of depressing. Disney got really cheap on us with the production value, and seeing fan-fiction where sad Ewan McGregor fights Halloween-costume Darth Vader at a construction site off Interstate 95 or something is just, well, sad.
As a general rule, both the Prequels and Disney+ Star Wars suck pretty hard, but the Prequels usually suck in more bafflingly “fun” ways, whereas Disney Star Wars just sucks in boring, depressing ways. Like, an example of the Prequels sucking is like “George Lucas actually wrote an entire Star Wars movie that didn’t even feature adult Anakin!” or “Obi Wan Kenobi rides a cartoon lizard while using a glowstick to poke a cyborg on a unicycle”. Whereas, with Disney, you get “lightsabers behave like baseball bats, everything is poorly lit, the cinematography is vomit, the music is boring and unmemorable, there’s like 3 new main characters that nobody cares about, all character development is replaced with Dave Filoni Rebels cameos, etc.”
You didn’t like Andor? Disney has made a lot of trash but I think it was worth passing it to them just to get Andor, Rogue One, and Mando Season 1 and 2, which are easily better than any movies or tv shows from the prequel era.
