It's not the engine. It's the computer-controlled fly-by-wire system that's vulnerable to EMP.
Given that modern turboprops use the same engines as jumbo jets the engines are equally susceptible to exactly the same things.
The reason for a turboprop and not a turbofan is the propeller's greater "torque" as it were. It takes a larger "bite" out of the air, enabling a
turboprop to take-off with a shorter run.
The reason for a tubofan (as in Airbus, 747, DC10) is it produces less drag, and can spin faster and more efficiently, allowing for increased cruising
and maximum speed and greater range.
Both the fan and the propeller are powered by jets engines.
To be truly emp-resistant you need control surfaces operated by hydraulics, not computers and servos.
I'm sure an aeronautical engineer can explain with considerably more accuracy.
