well if I'm correct Cable powers where compared to those Nate Greys, his alternate self, but that being said he wasn't the son of jean grey (Phoenix) so he couldn't possibly compare to having her abilities. He's more known as using his own hands on style then using his abilities, as they say a little neglected...so I don't think he would even be able to compare to the pheonix. Also, Jean Greys powers were repressed from at a young age to help her control her powers, Cable wasn't.
