ok, ok... Intellect and knowladge are different... so...
Cable as stratergests? he's had access to all the knowladge and used it.
It Cpt America had access to Cable's stuff would he be even better?
I think those that talk about characters having more specific fields of interest are right. Prof X can creat anything he imagins... not exactally but that is how its been discribed. But he's been focused on philosophy and social issues rather than Stark equivalent armor and weapons or Richards science adventures.
And in that way we believe as a species that "the pen in mightyer that the sword" Stark just created a sharper sword while Prof X was writing letter to the editor.
Now i'm not saying Xavier is smarter than tony or not - i'm just stating how i see it.
