He's beaten Surfer without Warrior's madness and one-shot 616 Hulk before. The caliber of enemies he's faced and even defeated are well beyond anything in the DBZ verse. Without jobbing Thor could beat Bills and Goku together. It largely depends on his mood. On earth he cannot use his power much like Z protagonists, but when he's bloodlusted or in space, he has galaxy level+ feats. And FTL reaction speed like tagging Surfer when they were both in hyperspace.
