Iron Man
(Bleeding Edge)

Attack Potency/Striking Strength: Likely around city level, as he was able to overpower Cull Obsidian, who was able to briefly overpower the Hulkbuster.

Durability: Asteroid level, as he survived numerous full-power punches from Thanos, as well as massive chunks of moons crushing him.

Speed: At around 600 or so miles per hour. His fastest suit goes at around Mach 5, and if we're scaling this to someone like Corvus, Proxima, and Cull, then... so I'm putting down this: ??? (Help is appreciated)

Lifting Strength: ???

Thor
(Post-awakening/Stormbreaker)

Attack Potency/Striking Strength: Island level, as he was able to briefly overpower Hela by bringing her below the bridge, and was also able to overpower the Hulk. W/ Stormbreaker, he is around country level, as he was able to nearly kill Thanos.

Durability: Star level. Was able to survive necroswords and weapons to the back, eye, and heart, as well as numerous punches from Thanos, as well as survive numerous wallops from Hulk. And let's not forget tanking that neutron star.

Speed: ???? (possibly at around Mach 100 or so with Mjolnir, as it was able to circle the Earth and come back to Thor in a few minutes, so if we're scaling SB to MN, then...)

Lifting Strength: Well, Star Level, since he is able to lift both Mjolnir and Stormbreaker with ease. Everybody else's mind (sans Groot) would have broken from the sheer power.
