I might be overthinking it but feel like Seinfeld was more a show about normal people who sometimes do shitty things - just like real life. I can’t think of anything truly horrible any of them did on the show, just a bunch of “social” wrongdoing. Telling a secret, sleeping at work, the perfect comeback, etc. It’s famously a show about “nothing”
Then IASIP is about a bunch of assholes riling each other up to be horrible for their own benefit.
I think Seinfeld is the more “important” in the grand scheme of television for it’s groundbreaking approach but in a vacuum, IAS is the better show.
Jerry purposely drugging his girlfriend so he could play with her toys was pretty shitty AND horrible.
Yes, but that’s season 9, which is after Larry David left as writer. While Larry David was there thru season 7 the characters were quirky regular people who sometimes made bad choices like all humans do sometimes. After Larry David left and Jerry Seinfeld was writing the show by himself from season 8 forward, the characters became much more fucked up, and the show was also way less funny
