High 1-B people (from what I can tell): Odin, Zeus, Skyfather Hercules, Thor with Odinforce, Base Herald of Thunder, and God Blast, Uatu (no idea how he scales to Odin or High 1-B but this is what I've heard), Moderately Fed Galactus, Doom with prep/tech and absorption
High 1-A: Rune King Thor & Herald of Thunder with Absorption and God Blast, Life Bringer Galactus, Ones who Sit Above in Shadow
God Emperor Doom would either be Low 1-A via scaling above the IG, or High 1-A since Reed with his powers brough back the Marvel Multiverse.
Low 1-A: Dark Phoenix (via scaling above Giraud due to being the most powerful Phoenix force host), Shuma Gorath, Ant-Man at max size
