Honestly, I'm not sure why drones aren't considered better for air superiority as well - better power to weight ratio, no human-imposed G limits, probably better maneuverability due to better wing area to weight ratio, potential for 360 degree vision, and without needing to worried about losing highly trained pilots, you could also explore making many more cheap drones that are individually inferior but collectively superior.
The dirty little secret in the USAF is that everyone knows drones are superior for fighters because of the human imposed G limit being removed, but its an organization run by former pilots and they hate the idea.
This is also why they require drone operators to be actual pilots despite the fact that there is zero need for that level of training. Its just a way to protect their idols.
Why would a normal jet fare any better in an EMP attack than a drone? Communication attacks, maybe, but there's no reason you couldn't have some limited level of autonomy to bring it back home automatically in the event of a comms failure.
