I am not 100% sure about this. In the 1990s, the Russian defence sector faced an acute cash crunch, and it affected the R&D. They came back strongly in the last decade or so, but I am not sure whether the Russian technology is capable of matching that of the United States. But as of now, the American technological advance has stagnated, while the Russians are innovating.
digitalization was just beginning. I am not sure that with the same materials the f22 would be the same if designed today.
anyway the SU motors make me think of this one :
when playing ADF
from my personal virtual experience playing :
I was always afraid of the mig 29... but the su 27... if I didn't lock it first it was often going bad... and then the f22 behave slowly... a litte fat. not aggressive enough to my taste.
but who knows. let's hope not to have to find out... IRL.
