Honestly, I feel like a lot of the GT apologia in this thread is more a pushback against Super than genuine praise. GT wasn't made from a place of "artistic integrity". It was literally born from Toei being unwilling to lay their then-biggest cash cow to rest. The entire first arc, one of the longest of the show, was literally "let's make Dragon Ball again, but in SPACE!", but it was mostly fun. Baby was a genuinely brilliant arc, but the shadow dragons were stupid, and not in the fun stupid way the majority of the franchise is.
But you know what? It's a fightan animu. I'm not asking for perfection. I'm asking for well animated fightan, which GT offered in spades. Super, in comparison, tossed two terrible recap arcs at us, in poorer animation than the movies, I enjoyed Goku Black if just because I'm a sucker for new Kamehameha variants (Black Kamehameha isn't as hot as 10x Kamehameha, but it's still bretty good), and watching the initially sinister Goku Black evolve into Goku Faggot and get god-buck-broken was hilarious. ToP was eh. Universe Survival was too long, but had some great fights, which makes it basically Namek but Goku seduces Frieza to his side with the power of frosted hair tips.
In short, at the risk of being a faggot centrist, both have their ups and downs. Moro was a really fun arc I'd love to see animated, though, even if it was kind of Buu 2.0, aka King Piccolo 3.0.
