For what it is, it's okay at best. Just take into account that GT is non-canon in part to Toriyama not having any involvement with this series. For curiosity I'd say see it, but it's easily skippable.
Man what a step back from the classic that is DBZ... But thats just because Akira Toriyama didnt have anything to do with this version
Not as good as DBZ but the final arc was epic
Okay, what I said about it being non-canon is the only good thing about this anime was ignorant. While it's true that it's non-canon, this anime is still pretty good, at least at seasons 2 and 3. Season 1 is pretty bad.
I'm probably the only person in the world who might prefer GT to Z. I just dig the tacky sci-fi vibe.
