If you are aiming your question at the modern stuff..................................I'm not a pilot, don't even know how to fly, but we have a family member who was flying F-15's for 6 years before transitioning to the F-22A 2 1/2 yrs ago; the first time I met him last Xmas, I asked him a bunch of question about that topic; what he told me; he was VERY big on the Eagle while he was flying it in Germany, ( even had an opportunity to "strap on" a Mig-29 while he was there )
I'm reluctant to say much about planes from different countries, because there are guys from "everywhere" on this forum, and I don't want to "rub anyone" the wrong way; when I asked my "friend" about the Mig as opposed to the Eagle, his answer was pretty "diplomatic" ! Like, "been training in the Eagle for a couple of years, know all about it's performance and capabilities, then only got to "scratch the surface" in the Mig for a few minutes. Everything he said about the Mig was positive; he ended that subject by saying.......if I ever have to go in combat in the Eagle, facing a Mig driver of equal training in his machine...........the Eagle will be "bringing him home" when it's all over with. ( Can't get much more diplomatic than that ! )
He also said that the Russian pilots were " extremely worthy adversaries" !
Then we got to the Raptor; he said the Raptor is hands down, the easiest plane there is to "fly"; ( which is definitely not the same as " going to war" against other highly trained crew from "other places"; this young guy was so much "different" from the standard "fighter jock" types I have talked with over the years it was amazing. Very small guy, probably less than 150 lbs, and probably about my height, and I have "shrunk" from 5' 8" to my present 5' 7"; he said there are "bigger guys" flying Raptors, but the thing is pretty "tight", not much room for the "driver". But as far as "performance"..........think of an NFL
team Vs. a Jr. college !
