Is a nuclear weapon a bigger threat to us than an Electronic Bomb?

These "E-Bombs" have the ability to completely disrupt and/ or shut down all computerized systems in their blast zone. With the ever increasing dependence of our military on completely computerized weapons systems including the M1-A1 Abrhams Tanks, the computer dependant B-2 stealth bomber, and F-22A Raptor would an E-bomb be more of a military threat than a nuclear warhead? Obviously, the death toll of a nuclear bomb has huge impact, but does the ability of an Electromagnetic or Microwave bomb to shut down not only our military fighting force, but also our infrastructure itself, have a more strategic superiority?
