Ok first of all......
Lets clear up some mis-information.
Su-37 has 3d Thrust vector control allowing for the nozzels to turn up to 15 degrees.
F-22 has 2d Thrust Vector control
flaps that can deflect the airflow, I don't know the angle.
The reason why you won't see U.S. aircraft with 3d TVC is because they haven't managed to make a seal to connect the engien to the turning nozzel
that can take afterburning thrust and temperatures, Russia obviously has.
Also as hydrolic control of the Su-37s TVC is a back up to set it back to strait, yes the F-22 has a better computer but that only means it does the
same things a bit faster(miliseconds if that), software is what matters more here. Finnally the Su-37 has canards which mean another edge in
manuverability, by the end I think it's pretty clear that the Su-37 takes the cake for manuverability by a long shot. However in long range
combat(which happens first) the F-22s stealth, radar and cruising speed should prove useful taking the Su-37 down at range. The final word goes to the
Su-37 though because you can buy nearly three of them for the price of one F-22. Why? because it was developped under a proper capitalist system where
the company invests in its own product!(sales to India and China helped fund this project) The F-22 on the other hand has been an R&D expence of the
goverment for years, no there's capitalism for you
