Apoc in the first one.
"I am......Apocalypse! Look upon the future......and tremble!"
Second one's a bit harder to gauge, IMO. Next to nothing phased Apoc (it took all of Earth's telepaths to beat him, IIRC), but he didn't face anyone on the level of the JLA/Supes. I'd probably go with DS because he faced a much higher tier of characters. Apoc in TAS, though= beastly, and probably more impressive there than his comic portrayals post the "classic" period.
TAS Apoc had better lines than anything Apocalypse said in comics, and powerwise was absolutely ridiculous -- totally invulnerable, energy projection powerful enough to vaporize the x-men in a single blast, etc. His lowest showing was in the Magneto fight, and he was still portrayed as more powerful than Magneto (ridiculous!).
Animated Darkseid brings nothing to this fight except class, and sadly, that is not enough.
