Immortal Hercules wins. Supreme Power Hyperion seemed to be around Wonder Man level to me, and current Hercules and Wonder Man are about equal. So Immortal Hercules has a definite strength and durability advantage, plus a healing factor and better fighting skills. The only thing Hyperion has on Herc is a massive versatility advantage, between his heat vision and flight. So i give Hercules a slight majority since i dont think SP Hyperion would be able to put Herc down with Heat Vision, so they would eventually get into a brawl in which Herc would win. Hercules 6/10.
