are you kidding? Destoroyah survived a tone of spiral rays while SG was killed by two.

Keizer Ghidorah was able to easily defeat the strongest Godzilla, and only because Godzilla was powered up he was killed.

besides like titan said Destoroyah and SpaceGodzilla have an easily accessible weakness while Keizer has no weakness and they only way to kill it is getting ultimate keizer powers which could be impossible by compare to getting ice based attack or just a strong beam.
