Saint Seiya is not consistently good, it has a lot of flaws and a really slow start, but it's peak are some of the most memorable parts for me.
The sanctuary arc, is a master class at introducing characters you never saw before properly, and being a instant hit.
Jojo however is a absurdly consistent for my taste, I wasn't a ep bored, o wanting for things to speed up, Araki is a crazy ass man that avoid shounen power creep, by playing weird powers instead of AP.
How many shounens a character from arc 3 could fight guys from Arc 5/6 without any power boost?
