in a straight up dog fight the raptor has thrust vectoring and 450 rounds of cannon ammo the su 35 has 140 rounds. the su 35 has more short range missiles. also will stealth make a difference in russias targeting systems for missiles .they also have a new back up coming to the sky's soon and the old supersonic lancer that can do mach 2.2 can fire 28 long range missile and coordinate with the f 22 raptor and fire from over 100 miles away.
they would travel in packs .also they might use a few f 16s to sucker the Russian planes . we also as I said are or may have already developed a gen 6 fighter.
