LO, I don't think anyone would say that the F/A-18, F-16 or Typhoon have the same EM. As it is well known that they don't. I think the included word, comparable needs to be taken into account. They are saying the EM is closest to the FA-18. I would put the FA-18 as comparable to the F-16 or Typhoon in EM.
The sims are run by USAF, USN and the partners. I wouldn't discount their professional assessment.
