Well I do agree that the storytelling was good but I will not say it was better because STAS had very good story in a lot of it episodes but both have their low points in story.
You seem to like the idea of power from Superman, and you know what? I'm with you. He's gotta be the biggest kid on the block with no second thoughts about it. The makers of STAS were very wrong headed in their thinking when it came to his powers and their relation to the story. But the idea that he should only rarely be tested in power and should only rarely be knocked down is wrong headed to me too. The idea that he is only as strong as he need to be has always been my motto. Guys can try and go a few rounds with him but they fail in the end. That's not to say that everyone and everything on earth should have a shot with no explanation though.
I think the Ruby/Spears Superman was good and it had a wide rage of stories being told in it, but it had no over reaching cohesiveness. STAS had this in the form of developing and returning characters who were introduced in the show (Supergirl, Darkseid, New Gods, Luminous who made a minor role in one ep then come back as a villain)
I feel the quality beats out the quantity here. Plus it will age much better and the themes and ideas can still get the kids of today into Superman way easier than the Ruby/Spears Superman can.
At least that how I feel.
