Norse gods are not inferior to Greek gods
I do agree that compared to the Norse Gods, the Greek Gods are more like natural forces. But that does not mean the Norse Gods are inferior. In fact, the Norse Gods can affect nature just like the Greek Gods.
Ymir is a natural force, as well as a being of pure creation and chaos. Yet Aesir such as Odin believed they were superior, so Odin slew him and used his body to craft multiple dimensions. Ymir’s magical guts and blood nearly drowned all of existence.
Thor can summon thunderstorms across the sea. He is so powerful that his clash with Jörmungandr shook all Nine Realms. The World Tree's very existence supports all of creation; every one of its strands transcends space and time, and its branches support all Nine Realms. During Ragnarök, Thor struck with such force that even the World Tree was splintered, sending Jörmungandr back through time. Even Kratos was stunned by this feat, describing it as “madness”. His battle with Laufey destroyed a Vanir town, tore apart a valley, and ripped apart locals' souls.
Baldur can absorb any element and evolve into a form immune to it. By absorbing fire, Baldur could become invulnerable to the Primordial Fire within the Blades of Chaos. His strength is also incredibly formidable. In his first‑encounter melee against Kratos, the two split the ground and changed the landscape. He also temporarily knocked Jörmungandr unconscious.
Heimdall can read others’ minds and thoughts, allowing him to dodge nearly every attack. Even though Mimir knew Kratos had killed gods greater than Heimdall, he still believed Kratos couldn't touch him. Kratos did not disagree, and obtained a specialized weapon that could overpopulate Heimdall’s senses in order to harm him.
Njörd can generate ferocious winds that whipped across the sea. As one of the high Vanir Gods, he wields Temporal Magic, which can stop or rewind time at will. This Temporal Magic once even halted the movement of the sun and moon.
Freyr, wielding Ingrid, temporarily held back Ragnarök’s final blow, which destroyed Asgard and shook the World Tree down to its roots. He also blighted the lands of Asgard by reversing his enchantments.
Freya is a master of Seiðr magic. This power can confuse foes into fighting one another, commune with nature itself, defy the natural order and summon the dead to her will, corrupt and even reshape souls. Because of her curse, Baldur obtained invulnerability to almost anything.
Yeah, none of this can match the Greek Sisters of Fate. No Norse god can manipulate fate the way they can, but neither can any Greek god. The Sisters of Fate are not Greek Gods, and they're above the gods. It was they who caused the Titans’ defeat in the Great War; in other words, they manipulated the fates of the Greek gods and secured their victory. That Norse magic cannot rival their power does not make the Norse gods inferior to the Greek gods.
Besides, if Norse gods are inferior to Greek gods, Tyr wouldn't be one of the strongest gods Kratos has ever faced right?
