I agree that on average, we are more sophisticated in all ways...but that is a double edged sword, as the saying goes.
We are very much more dependent on such systems. If we lose that advantage, we are more degraded than the Iranians will be if they lose that. Just ask yourself: If you gave the Iranians the choice of both Iran and US losing their military capabilities dependent upon "cyper-power," would they take that? Of course they would, because they know it would hurt us more than it would hurt them.
And that, by the way, is why they want nukes. I don't think they ever envision destroying New York City. Rather, they want the ability to pop a high altitude EMP nuke to knock us back 500 years in ability to wage war (and to feed our people).
