I agree, Earth-X =/= Earth-Quality. I disagree, it's not almost all Earth-Two. Earth-X is as different from Earth-Two as it is from Earth-One.

Yes and no.

Roy Thomas played a retcon game using All-Star Squadron. He put almost all the character DC owned at the time (1981) that were published in the 1940s on Earth-Two. That included all of Quality's characters. He showed that Earth-X had no native super-humans c. 1941 and then in 3 staged "migrated" the Earth-Two versions of the Quality characters to Earth-X.

The end result is that, while Earth-X is a part of the pre-Crisis multiverse, almost all of the characters associated with it are as native to it as Black Canary and Red Tornado were native to Earth-One.
